Is splashthat.com Safe?

Watch out for this site's promises when it comes to their "pro add-ons". Their site currently states that they can "BE PURCHASED FOR A ONE-TIME FEE THAT CAN BE APPLIED TO ANY EVENT YOU’VE CREATED. EVERY SPLASH PAGE LIVES FOREVER — YOU’LL NEVER INCUR ANOTHER CHARGE FOR A FEATURE YOU’VE ALREADY PAID FOR." However, when I contacted them via email to double check I was told that this is not true, in other words. You'd have to pay for any of these pro add-ons every time you create an event, therefore the paragraph above is quite misleading to say the least. I have saved all the email correspondence between me and them for whomever is interested in verifying my comments and rating of this site. Furthermore, their customer service guy, Kevin, is excruciatingly slow at replying to one's emails. And when you call their number, nobody answers, you just get a recording and voicemail to leave a message.
