Check you telephone ID number and never ever answer their calls. I don't ever answer them and eventually, after about 3 months they stop calling and sell it to someone else.
Call several times a day and I already added my number on the do not call list, apparently it did no good. This is my cell and I am working when they call.
Asset Acceptance Collector - They have bad data for an account I never opened, never held, never used and never was responsible for - That was opened after my divorce... They think calling me 6-million times a day will guilt me into paying for a debt I am not responsible for.
