Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

APR or interest rate Texas

I was told I was receiving a 24 month promotional period for my enrollment and I only received a 12 month promotional period. My original purchase was $2200.00 and after over a year of making payments each month, my balance is now $3000.00, more than the original purchase and the interest accrued is roughly $1500.00. This should not have happened as I was told I was receiving a 24 month no interest promotion.
