Hello all! I am having some issues removing myself as an authorized user from a trade line with AMEX and one with synchrony WM MasterCard. A "friend" of mine added me as am AU on his AMEX gold rewards and Walmart CC while back. Let's just say, due to his moving to a correctional facility, he has not paid his now maxed out cards, and it is wrecking my rebuild. I have called sync and AMEX both, and I can't get anywhere with either. Sync keeps telling me they cannot locate any account info with my info on it, and AMEX keeps telling me they have removed it but no joy. I have disputed with CBs also with no love. Any suggestions!?
