Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Billing disputes Hawaii

I applied for a - card. It had an introductory offer of - miles if - dollars was purchased on the card within the first three months. I did this and redeemed my miles. This card also had an annual fee. I paid all outstanding debts and I cancelled my card prior to the annual fee taking effect via a phone call to the credit card company. I was assured by the operator that I would not be charged because I cancelled within the time frame prior to the fee taking effect. The credit card company has since changed owners and is now a Master Card and is operated by -. For the last 2 years or so I have been receiving bills for the annual fee. I have made several phone calls to customer service explaining that I am being mistakenly charged and am always assured that the mistake will be corrected but I continue to receive bills. I was recently inquiring about taking a second mortgage on my apartment when it was brought to my attention that my credit score had lost about - points since the last inquiry and that it was due to this issue with the outstanding credit cared payment. I have always had excellent credit and always pay my bills so this is very bothersome to me. I believe that the credit card company intentionally refused to fix their mistake hoping I would pay a fee that was incorrectly placed on my account. I would appreciate any help available to fix this issue. Thank you.
