I had a similar calls from the guys with the accents. They said I had taken out a payday loan online and owed money and I was going to be sued and taken to jail. I said no, I never did the loan. I had filled out an online application but did not take the money. He asked how I could prove it...I said with my bank statements that would prove I never recieved the deposit.
What worried me was thus guy had the last 4 of my social and my bank account. He wanted me to confirm them but I would not.
When I called the AZ AG office, they actually asked if they could pass my name and numnber to the FBI as they are investigating it. When I talked to the FBI agent he said that these guys move so fast they have a hard time tracking them down. He also told me it is easy for these guys to get the last 4 of your bank account or social. it makes them more believeable with that info. He siad they would eventually try to get me to give them the rest of the numbers through a settlement agreement.
After I talked with the FBI agent these idiots called back. I told them I had reported them to the AG office and that seemed to have worked. They are no longer calling me.
