Synchrony Financial Credit Reporting Complaint

Synchrony Financial Credit reporting department,

Incorrect information on credit report Account terms Illinois

Synchrony Bank/JCP, are stating that I have not been sending in my payments when I have been mailing through my bank checking account every - Wednesday of the month since I have had the card. But in the last 3/4 months I have been getting statements saying I have not paid on my account. I originally owed $330.00, in which I have been sending a payment of $30.00 each month ( I do have the bank records to show this ) but Synchrony have been sending statements that they have not received this money and adding on ridiculous fees & charges bringing my account to the $420.00. I 'm a - on a fixed income and I do n't need the this type of trouble. Please help
