Capital One Credit Card Complaint

Capital One Credit card department,

Delinquent account Maine

As of -/-/15, Capital One Bank issued a - ( Cancellation of Debt ) to me for an old credit card account that they had charged off. I claimed this income on my 2015 - and paid taxes on the amount. However, Capital One continues to report a balance owed on that account as well as actively reporting the account. I have requested of them to update this information and not only have they claimed the amount is correct, they have now entered a dispute status on my credit report for something that is THEIR error. I have attached a copy of my credit report showing the balance still reporting, my letter to Capital One asking them to update my account, a copy of the - clearly showing the account number and a copy of the response letter that I received from Capital One. I am not disputing the validity of the account from the past but do not feel that they have the right to continue to punish me and destroy my credit for something that I have paid income taxes on and they have written off as bad debt. They are still attempting to collect on this debt which I am refusing to pay because I have already had to pay taxes on this amount for income, why would I pay them as well?
