Citibank Mortgage Complaint

Citibank Mortgage department,

Home equity loan or line of credit Loan servicing, payments, escrow account California

I had a HELOC with Citibank in 2010 that was charged off but no document was sent to me that provided the filed date. I am attempting to retrieve a document with the charge off date as the credit bureau has it incorrect and/or is unclear about the date. I have spoken with - different people in - different departments always being transferred from one person to the next. I have sent 18 requests via fax since Thursday, - - with my information to confirm receipt. I have not received any communication from them from those requests. All I need is a document with the correct charge off date so I can have my credit corrected.
