What to do next

I closed my account and sent out letters the end of May. For the most part the PDL companies have left me alone. Except for Ameriloan and Advantage Cash Services. Both have been paid well over the original amount of the loan. I have reported them both to the Attorney General and the FTC for repeated phone calls (even after I asked them not to call anymore at work) and threats. I have gotten no where. They still call at work and at this point I am sure my co workers are getting sick of it. Can anybody tell me what to do next. I don't believe they can really do anything to me it is just getting really annoying. Thanks for the help.
