Care Credit GE Moneybank deceptive practices to charge high fees Internet

I signed up last year 2010 to Care Credit owned by GE money Bank for some dental work that was $468. I'm now learning this was a big mistake as Care Credit despite stating they had errored still require me to pay their high fees for their mistake.
Back in August of 2010 I made my payment on their website like I normally do and twice when making a payment since I have had their service their website sometimes would give an error which would give infor to call a number that does not work but to play it safe I would check my bank to see if any trancactions were processed and if not would try again. In august I had made my payment online and had gotten this error for a second time and looked at my bank statement online. It showed GE moneybanks payment had processed and was pending to printed out a copy for my records. Almost two weeks later the pending amount fell off and was never charged and when I logged on I noticed a late fee so called them and sent them a copy of my printed statement showing their error that they even adknowledged. I paid the monthly payment again plus the new month we were in minus the late fee and instead of fixing this issue they hit me with more late fees and after several calls they still refuse to fix the issue plus as of February they added on so many fees the $468 has turned to over $1100 plus they have not only called my home phone 7 times+ a day they call my medical phone as well which is my mistake as I used it to call them and they got the second number via caller ID. I have now filed a small claims subpoena electronically against them and am awaiting the court date.
