I'm at my wits end and don't know what to do!!!!

about a month ago I recieved a call from a Michelle Hawkins and Anthony Hopkins several other individuals (one was Anthony Hopkins (supposedly))with heavy indian accents saying that I took out a payday loan owing them originally $500, a day later they called saying I owed them $600, and the day after that $800, etc. I told them that I haven't taken anything out in the last year and a half and I called my bank immediately, because they stated that I needed to pay them that day or they would see me in court that following monday. I told them that I talked to my bank and nothing was transferred into my bank account and the guy (hopkins) said that he would see me in court! I asked him where was I supposed to report, because I was never subpeona'd and he said that was up to the judge and hung up on me. I called my sheriff's department and they gave me the number to the FTC and the BBB I filed a complaint with both agencies and got a reference number and gave it to them, they continued to call my place of work repeatedly and Hawkins went so far as to call one of my co-workers an "f*ing liar" because I wasn't at work. the calls stopped for a little bit, but I just recieved a call from hawkins today (she called from an unavailable number so now i can't trace the number she called from) as soon as she stated who she was i hung up on her and she called me at least 5 times within 10 minutes, she then proceeded to leave a voicemail saying i had 24 hours to get a lawyer and call a number 818-296-4010, stating that an investigation is being taken against my place of work, my "references", my drivers license, etc. and she stated that if she didn't hear from my attorney TODAY "that she wishes me luck in court". WTF????????? what do i do I know it's a scam but now they are threatening my AGAIN, and I don't know how the hell to get rid of them, I've already reported them to the better business bureau, and the federal trade commission, i don't know what to do now, do i file a complaint with my sheriffs department, change my number?? what do i do because every time they call i lose more and more of my patience and i've already got enough to stress over, i'm at my wits end i don't know what to do. HELPP!!!!
