Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

APR or interest rate Kentucky

Synchrony Bank purchased the BP Visa Card program and raised my interest rate to over 27 % on outstanding balance and purchases. I called customer service to request some explanation and a lower rate and they said they can do nothing. I am in a position where it is difficult to pay the balance right now, but I seem to be stuck paying a huge portion of my payment each month to interest.
