Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

Payoff process New York

I set up an account with Synchrony bank through Amazon.com. I set up recurring payments on this account so that the entire balance would be payed off each month on the statement date. Two weeks after a recurring payment was set to go through, I check my balance and see it is far higher than I had expected. It appears the last recurring payment had not gone through and I had been charged both a late fee and interest. The only communication I had received from Synchrony during this time was an email on the day after the payment was scheduled informing me that a payment had been posted. At no point was I informed that the payment had not been completed.
