Hi...recently I had a man call me from a place called PSI, a collection agency. he claims that I owe them money from a check I wrote in 2010. I mentioned to the guy that I had paid all of my debt off last year and probably already paid them. He was very aggressive and mean. He keeps calling me at work every hour on the hour. I explained to him that I was not going to pay anything unless he showed me what I owed. Anyways, now he threatened me and said he would have me arrest for writing a bad check. He said he would file the report with the san Bernardino county sheriff. today, my work called me on my day off and told me that the sheriff dept. called looking for me and that they would send someone out to see me. Not sure if they are actually allowed to arrest me for something that happened in 2010. Not sure what I should do?? I called the san Bernardino county sheriff dept. to see if this was legit. They were not able to help me since I did not have any information. Should I worry?
