This is a user-to-user forum and I doubt someone would call you. When you say customer service has yet to help, does that mean you’ve been on the phone for hours and hours with people in India and/or similar time with the same people on a chat session while they talk you through various things, and none of those things have helped? Or have you not gotten through to anyone from customer service and found this forum?
Adobe provides a 30-day trial for most of their products, so if you paid for it without testing it on your computer, that is not Adobe’s fault. Most credit-card companies can handle refunds within 30-days, and if you didn’t do that, it, again, is not Adobe’s fault.
If you provide some details about your system it is possible that someone here might be able to suggesting things to do to figure something out, but it may not be more than what Adobe Support did with you, already, if you have spent a bit of time with them.
One suggestion I would have is to run the Adobe Log Analyzer to see if it finds anything. And if it doesn’t, at least look at the installation logs to see what they say about the install failure.
