GE Capital Retail Credit Card Complaint

GE Capital Retail Credit card department,

APR or interest rate New York

I made a $900.00 purchase using my care credit card. I was granted 12 months of interest free payments for that transaction. Once that promotion ends, I would be charged 26.9 % on the remaining balance. During the course of the year, synchrony bank took over Care Credit. On -/-/-, my balance was down to $350.00. This company charged me 26 % on the original balance which is not on the terms I agreed to when I first joined this company as Care Credit. I contacted Synchrony and the rep told me that she could n't tell me my new interest rate/agreement. I told her this was deceptive as I had not signed these terms nor agreed to them.
