USA Fast Cash International detective, lawyer told me they were a detective, have me arrested if I did not give them 295.00 Internet

 On Aug. 18th on my home phone number a man stated he was a detective that my name and the last four of my social security number have been involved in a illegal action and he was here to investigate by saying that Fast Cash International had put 250.00 in my account and it needed to be paid back but that was going to cost me 295.00. Well I told him I was going to contact my bank and he gave me a number to call him back and advised me they closed at 5:00pm. I had better get back to him before the end of the day. 
I called my bank and of course there was not 250.00 that had been deposited to my account and they would send me the statement. He called me back on my cell phone and stated that thye were going to arrest me I could not possibly have a bank statement that fast so he advised me to get it taken care of and hung up on me after yelling. Then left a mean message on my voicemail on my cell phone which I did not answer when the number came up. He called the next day to tell me he was a lawyer and they were going to have me served and arrested by Friday and asked me if I had gotten a lawyer and I told him no and he proceeded to tell me how serious this was and I did not want to go to jail I needed to take care of this. Then I asked him what all the noise was in the background he said other lawyers working, and started yelling at me again about that does not matter I needed to take care of my business and hung up on me again. I realized at that point it confirmed to me  that  noone would be this unprofessional as to yell and hang up.It is now Friday and no one has come to get me.
