Capital One Credit Card Complaint

Capital One Credit card department,

Billing statement Arizona

Requested copy of statement that show the credits that changed the reporting balance from $2500.00 reported - 2016 to $1900.00 reported balance as of - 2016. I sent a direct request to Capital One requesting the statement for that change but never received -. I did receive a letter saying Capital One was going to change it but never the supporting Credit Card statements showing how the account was credited. Also could I get a verification of the correct address and furnisher name as it would appear on my credit report for account number as reporting in my CFPB complaint.
