Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Billing disputes California

I disputed a charge on my Visa card from - - back in -/-/- in the amount of $2700.00 for a keyboard I had purchased that did not arrive in the condition it was supposed to be in. The keyboard was returned to - - and the amount was credited back to me. In the meantime, my Extra Points Visa Signature Card issued by Barclaycard continues to charge my account for the above stated amount despite the fact that I have complained numerous times that there was only - purchase, it was returned to the merchant and I do not owe any money. I do not have anything in my possession. I was told by the agent several times that it is an error on their part and it will be escalated and removed from my account. This has not happened. Since -/-/-, the charge continues to appear on my account. It is affecting my credit score and is wrongfully subjecting me to a liability I should not have. They are doing nothing to resolve the problem and I require assistance in getting this cleared up permanently.
