Received a call from XXXX. When I answered there was no one on the phone and after several seconds the caller hung up. When I called back a man answered and did not say the name of the company or that he had called me in an attempt to collect a debt. He told me he was calling about a payday loan I had taken out with XXXX XXXX Loans in XX/XX/XXXX. He said he wanted to know what I was going to do about it. He never told me the name of the company that he was calling from but told me that he has tried to contact me several times which is false. I have had the same phone number for over 10 years. I told him that it is now XX/XX/XXXX and in the state of Arizona payday loans are illegal and he should not be contacting me regarding a debt over 7 years old. Once I said the word illegal he seemed flustered and said that he had to terminate the call. Then he hung up. In the past I have taken out payday loans but I do not remember taking one with XXXX and I do not recall how much the loan was for. The man I spoke with said my account number ended in XXXX digits and when he said the XXXX digits they were the last XXXX of my ssn. Now I am worried that I may have a identity theft issue
