I purchased a XXXX TV ( {$890.00} ), TV stand ( {$170.00} ) and wireless adapter ( {$58.00} ) from Best Buy XX/XX/XXXX and the purchase, totaling {$1200.00}, was considered a " same as cash plan '' with no interest financing for 36 months. I made regular, timely payments every month to Best Buy ( normally exceeding the " mininum balance due '' reflected on the statement ) and on my XX/XX/XXXX statement showed a previous balance of {$1300.00}, a {$200.00} payment, and interest charges of {$1200.00} ( 96 % of the original purchase amount ). I have been a loyal Best Buy customer for decades and have utilized their " no interest '' offers on many occasions, being charged interest at the end of the program period only on the UNPAID balance - in this case {$380.00} - not being charged accrued interest on the entire amount for the entire program period. I was informed this was due to the Best Buy 's change to Citibank MasterCard as their financing servicer. As I never ACTIVATED my Best Buy Citibank XXXX ( I still have the original credit card received with the activation sticker on the front ) and was not informed of the change in the financing terms, I would request CFPB advocate on my behalf with Citibank to adjust the interest charge to only the UNPAID balance. 
I sincerely appreciate any help or guidance your organization is able to provide.
