First Cash International John Told me I had a list of charges against me Irvine, California

I received a phone call today on my cell phone and my work phone. A voice that i could hardly understand told me it was urgent that I call back and to not avoid this message. I called the number back with an idividual who could hardly speak english, he began to read me information and told me not to interuppt him. Basically I had a list of charges being filed agains me that included theft, money laudring, etc...he had names of friends that I have listed as references when applying for items on line. He told me I had accepted money from a payday loan service and had not paid the loan off. I told him I had no clue what he was talking about and he said he would send my criminal report to my boss!

As I was on the phone he told me he was with First Cash International, JOhn Connor & I googled it and told him this was a scam and he got angry and told me if I thought ti was a scam then to hang up and not call him back.

I'm concerned something is going to be sent to my workplace. He asked for my attorney's information, I don't have an attorney and never received money in my account!

Should I be concerned?
