Citibank Debt Collection Complaint

Citibank Debt collection department,

Credit card Improper contact or sharing of info Talked to a third party about my debt Nebraska

This matter involves an account initially handled by ExxonMobil and assumed by Citibank. I was trying to work this out with Citibank when they referred it to - -. At one time both were trying to collect the same debt from me. Then - called my ex wife and discussed the debt with her. She has never been a cardholder and has no interest in this account what so ever. I do not understand why - would bother her when she is my ex wife, they had the correct address and phone number and all account info. This appears to be a problem with Citibank accounts and the vendors they use for collection.
