I just got call from same number and a women told me she was from consumer service and that unfortunately someone had filed a complaint against me. She was going to give me the phone number of the legal office handling the case where I was supposed to call I just told her I did not believe her and hung up, for I know that if there were a legal office with a case they'd for sure be calling me directly.
Last time I told someone with similar call to brush off the party got very obnoxious.
