I attempted to notify the person calling of a change of address and they told me it is not their job to keep that information. They were supposedly sending information to an address that I have not lived at for 10 years. My family is receiving threatening phone calls and i have received emails threatening to take my exempt income, lose my job, seize my retirment fund and so forth. I tried to speak to a supervisor who told me the same thing, that it is their job to basically hunt me down, not help me. They were threatening to file papers with XXXX XXXX and again I asked to provide a new address and they refused. I received no bills from a collection agency in reference to this matter and I asked for them to mail me a copy, and they refused. They said they made an offer and I refused it, which I did not, I asked for them to speak to my mother and instead they refused to work with me or her. She tried to talk to the supervisor and he was very rude and hung up on her. To date I still have received no copies of bills, only harassing phone calls to my family and threatening phone calls to myself.
