Credit management company has called multiple times in the past 3 weeks alleging that I owe money ( apprx. {$300.00} XXXX to XXXX. When I inform them that I do not have a XXXX account they ask me for the last XXXX of my soc. # to 'verify the account '. I refused and said you give me the last XXXX digits, and I will tell you if you have the right person. They said they could n't do that. They said well perhaps it 's identity theft and we need to verify that. They said have you ever lived on XXXX, and I told them no. I told them I would run a credit report to see if I had any fraudulent information and to stop calling me or I would inform the attorney general of Michigan. They have called back 3 more times, and I have put a block on my phone for their number. I ran XXXX credit reports and there is no XXXX account or any other suspicious activity. The number they are calling from is XXXX.
