Capital One Credit Card Complaint

Capital One Credit card department,

Customer service / Customer relations California

Capital One does not want to provide information regarding my account. I understand they could not provide the info due to a recent identity theft that happened to me. They are requesting for me to provide documentation to prove my identity. I provided documentation but Capital One is saying the documents does not match the address they have on file for me. The address they have for me is " - -, CA '' which is for a closed account I had with them before. I applied for a new credit card last year with capital one using my - - address. I have called them numerous times and will not help me until I provide documentation with my " - -, CA '' address. I have not lived in - - for over 10 years.
