Capital One Credit Card Complaint

Capital One Credit card department,

Billing disputes New York

I spoke to customer service and a suporvisor that said on the call they see it was corrected and they were going to far over the letter of good standings ( never got a fax ) and then they came back to - with no change ( makes no sense ... ) it should be off my report! I have spoken to them numerous times and they say one thing than go another route ... It was from so long ago and i believed at those times it was corrected ... i do not have doc on it bc it was so long ago! But i am hoping they will finally admit what they say on phone and take OFF this inquire finally thank you!
