Cablevision is running a shady business. I was baited and switched by their sales department and then had a collector try to extort payment for a broken service before my bill was even due. Cablevision cannot deliver what it promises. I opened a business Ultra account. I was sold "the best they had to offer". This package was to include UNTHROTTLED (meaning you get the full 100 mbps the whole time) Internet, FREE TV (according to sales) and business class phone, which was to include various types of anonymous blocks, etc. and a static IP router which "should not affect your performance" (I figured 10-15% overhead, which is acceptable). What I received was a router that cut the Internet signal in half, a broken tv signal that literally caused the picture on every channel to glitch out regularly (several times a minute) and most of the phone features did not work. I own a modern tv, PC, etc. so my equipment is fine, not to mention it worked as expect with the prior ISP. I called and complained, several times. I could NOT GET A MANAGER OR SUPERVISOR ON THE PHONE, nor could I get a call back. For a business class service, this seems to be rather unprofessional and suspicious. So the first guy I talked to told me that they knew of the router issue "and would be working on it next year". Ok, so take back your router. Well, after a half of a month of trying to get even close to 100 mbps service (I was getting 50-70, router or not), I request a refund. Supposedly, there is a 30 day no hassle guarantee. I was given a 20 dollar credit. I was told my bill would be 600 dollars. Mind you, no bill in writing and their website usually is not accurate in my experience with their billing, so I feel I need a bill in writing since they are incompetent. Now I'm upset. So after another several rounds of calls and no supervisors or management, I finally get a "supervising tech" to credit me 100 dollars and change, with a change in the pay by date of the bill to the end of the month. Keep in mind, this all has taken place in three weeks or so. I never get a bill in month one. Ok, I figure its a day late, it came within the first few days of the following month, on a Saturday. On Monday, I am on the phone with a prospective client when suddenly my modem resets. So I go to check my voicemail and my accounts are locked. Come to find out that even though the bill date was two days prior and THEY made the billing mistake, my accounts were frozen. Keep in mind, in writing, they give a net30/net60 term of payment, so I didn't think I needed to pay the day I got the bill, especially since it had a pay by date of the 15th of the month I received it. On top of that, I re-read my bill, I'm being charged for broken tv and no credit applied. Even though the tv was supposed to be free and that was the excuse for the lousy signal. Get on the phone again. Get billing. Get told nastily that my account is to be shut off the Friday of that week and I need to come up with everything, with no credit taken off the bill. When I tell this schmuck my situation, he tells me "you should have gotten a notice, I don't know what to tell you". Meanwhile, my bill says I have til the 15th of the month to pay (this took place around the 5th). When I bring up this point, he tries to extort the friggin money out of me and gets lippy. Ask for a supervisor, get told for the third time in a month I would get a call back. They had to "review the tapes". Still waiting for that call. So now I'm livid. If I am offline, I am sitting on my hands. So I call back again, get apologies, they will honor their bill. That's big of them. BUT my voice service, still locked, I'm still a collections account. Meanwhile, for all their claims, I just received this so-called shut off notice a day before writing this. It states it was sent the 6th of the month and it is asking for the wrong amount of money again. So once again, the collector lied. Anyhow, as far as my voice service, they start backpeddling about their "automated system" and nothing they can do, blah, blah, blah. BS. Another call back (one day took me about three hours with them by the way). This time I get a woman on the phone and blast her a new a-hole, apologizing the whole time cos I am not mad at her, but her company. She tries to get me to pay early. I laughed at this point. I saw the Internet hit 99 one day. I understand that there are other factors in aggregate rates, but this thing rarely worked consistently is my point. Some days 50, some days 99, some days it would not stream ***** was inconsistent. I know how to do a bandwidth test, so take it from that perspective. They deny it, but after they claimed I was a late account, all my services started acting funny. One tech even admitted billing will start to lock services and play with your quality. It is despicable, unforgivable, and unprofessional especially in light of the fact that their claim to a billing delinquency was caused by their automated system and the refusal of management to honor its own billing system or its sales department and customer service department's word. If I have no bill and the techs are telling me your due by the 31st and the bill in writing shows up the 3rd, what am I paying. I don't care what any of you say, I want it on paper, literally, so if there are mistakes, which there were, there is no way for them to weasel out, which they tried. The rep tries to get a supervisor to talk to me. Another review of the tape. Another wait. She calls me back from an anonymous number (didn't even answer the first two times, thought it was a sales call, half the time you answer and no one is there), but no supervisor and says "they can unlock my account til the pay date in five days". So for a month or 6 weeks of service, I received a crippled service, was told I was a deadbeat and spent days on the phone with them for an hour or more each session and a 750 dollar bill. And their business services boil down to coupons to a few business like websites and loads of vendor calls. When they contact you, it is from an unknown number, so you don't if its them or a salesperson. They claim you can contact a specific rep for support, but that is a complete sham too. I tried, I got told "this is a virtual call center, we can't get a specific rep". Thanks a lot! I am not going to tell you who to go with. I myself went with FiOS, where I came from. I had an argument with one of their techs at one point and Cablevision swooped in like the town pump when a married couples argues. I was deceived and they never rectified. They are a bad company with the most shoddy service I've seen and I've used most of the "best" packages from Verizon, Time Warner, and Cablevision. They suck as a residential carrier, they suck horribly as a business service and I URGE YOU TO STEER CLEAR OF THEM. Cablevision, half the service at full price.
