Complaint Review: Criminal Justice Legal Law Service

I was contacted by a Kevin Williams, Kevin Johnston and today someone named Brandon something. The man had a thick mid-eastern accent. He had my social and lots of info about me. He was calling to state 3 allegations against me and when I got angry as he called at 6 am California time. He said that I had received a payday loan and had frauded a place named as Cash Advance, I stupidly had been shopping the internet for such a loan but was never given any money. I was told by my bank to change my account as there were charges being charged to my account I did not recognize. I did so filed the names that were not recognized with fraud dept. I have a new account. I have a payday loan that is paid monthly and on time with a company in good stading using fair practices. Now I am getting these calls and the same person using another name and phone numbercalls this morning and says police will be here to arrest me. I am calling an attorney but have not heard back. I am frightened as I have heard people have actually gone to jail till it is sorted out in court. I have done nothing wrong. Can anyone stop this from happening?
