Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Closing/Cancelling account North Carolina

I had a credit card with Barclay Card USA which I asked them for full balance for payoff so I could close the account several months ago. I paid the amount they provided as the payoff and closed/canceled the credit card. I received a bill today from the credit card company and when I called them about it they would not provide me any information. Once I paid off the payoff amount they provided and canceled the card then nothing should have charged my account.
