Is worksforweb.com Safe?

Customers set up accounts but getting the software to work properly was a nightmare. The support was less than helpful. The worksforweb software is like walking through quicksand. I tried installing it on another server but it wouldnt install i got an error message. The PHP version installed on your server is ***** However, iListerPets requires PHP version 5.4.x. Please ask your server administrator to install PHP of the required versions. IF the php version running was a lower version I could understand but it was only a few ammendments up. They Said: you may want to order our custom support service based on our $60/hr customization rate. I think this is really bad support after you have paid $399 for the script. Also the licence they issued me didnt work, but to get any more help from them. $60 per hour. The lack of interest from the support certainly shows in their replies to you. leading you to the 'if you want any more support' $60 per hour. The last message i sent them has been read but they have not replied, I think they are now stonewalling me. I could go on about the problems I have faced but I think this is enough for you to get the message. I have had to buy a script from another company as I have no trust or confidence in WorksforWeb.
