GM Financial Consumer Loan Complaint

GM Financial Consumer loan department,

Vehicle loan Taking out the loan or lease California

In -/-/- my ex spouse and I were purchasing a car, where GM financial required me to co-sign on the loan. In -/-/- we split and I called GM to take my name off of the car loan as I was not a primary borrower. For a while account was not reporting on my credit but my ex let the loan go and the car was sold out at the auction. GM tried to go after me for a balance as they claim and up to this date they are harassing me with calls and letters trying to collect on the account which is NOT mine. I requested a validation of debt and they fax me a copy of - stating that debt was a charge off and they filed a - in my exs name. However, they are trying to collect on this charged off, cancelled debt from me in the amount of $12000.00. I disputed this account with all - credit bureaus, however GM is still reporting this account with outstanding balance, which is hurting my credit report in a major way. They are refusing to report the balance to be $0.00 even though it is a charged off, and cancelled debt with - filed to IRS, and they are refusing to remove this account from my credit report, which it should not be reporting in first place since I was NOT a primary borrower on this car loan. I have written - letters to GM by now and have called several times and all my cries and requests for deletion of this unfairly and un accurately reporting account went ignored.
