I had a dental issue and paid for it using CareCredit.. now Synchony bank. the account had monthly payments that were supposed to be {$90.00} a month, zero interest for XXXX years. I make bi-weekly payments of {$50.00}. At some point an additional charge was added that resulted in my payments being short and subsequently lead to late fees of $ XXXX/month and interest. I did not authorize this charge. I made numerous attempts to correct this and on several occasions have brought the account current and still disputed the charge that I did not authorize. Finally after nearly a year, they removed the charge but did not correct the fees and interest that had accrued or credit any of the fees or interest back. My account is still short, still being charged late fees and interest ... and my promotional period is about to end which will result in huge charges if not paid in full. They never even sent confirmation of removing the erroneous charge In fact on the same statement the charge they still charged me interest.
