GE Capital Retail Credit Card Complaint

GE Capital Retail Credit card department,

Billing disputes Missouri

My son fell - the dentist insisted we use the Care Card in order for my son to treated originally the cost was - per - but when we returned the cost was the max amount the card had qualified us for. but I tried paying as much as I could a month then I contacted the Card Bank and they agreed to close the account and let me pay off the balance at - a month while making regular payments of an established amount 64.00 $ .Carecard increased payment amount and when they only received 64 $ they added 35 $ fine. They have been adding fee after fee adding it not to the overall balance but to the monthly payment making it very difficult to know exactly how much the payment needs to be and if the amount is not correct they fine you.. so I have been paying on this for quite a few years and they reactivated the account so they could increase the interest and charge more fees. I will pay off the card at the agreed upon amount of - a month the amount should be no more than-- at this time. However they just keep charging me more. I have contacted several service reps at GE CAPITAL RETAIL BANK/SYNCHRONY BANK
