Capital One Debt Collection Complaint

Capital One Debt collection department,

Credit card Cont'd attempts collect debt not owed Debt resulted from identity theft California

I received a letter from Capital One indicating they suspected I was a victim of identity theft. I talked to them over the phone and they promissed they would resolve the situation by doing their own investigation. after that I received another letter which states that they concluded the investigation and they concluded that I am responsible for a debt of over $4000.00. I have tryied to contact the Fraud associate that was assigned to my case many times and left multiple messages. I have never been able to reach her or get to a resolution. I have called Capital One and try to speak to someone else, but they keep referring me back to the same person and noone seems to care to assist me. today I have filed a police report.
