Litigation..Theft..Arbitration

Last evening my boyfriend recieved a phone call from a Investigator Stokes, saying asking if he was in on part of internet fraud and all that hoopla with me, they gave him a website to have me e-mail to tell them that none of my references we in on any wrong doings with me or they would be getting a subpeona. Now I dealt with another bunch of who haaas claiming all this crap, now when they asked what state they were in he would not answer, but I got the phone number and e-mail. Should I use the e-mail and tell them th same thing I had to tell the other one, to quit harrasing my family and friends and that I will contact my AG and so on?
