Consumer Portfolio Services Debt Collection Complaint

Consumer Portfolio Services Debt collection department,

I do not know Cont'd attempts collect debt not owed Debt is not mine New York

Consumer Portfolio Services ( - ) - Calls me periodically and asks about if I know where some person I 've never even heard of is and what he 's doing. They are INCESSANT about calling me even after I 've told them I have no idea who that is and that I have no outstanding debt with anyone and I 'm on a do not call registry. I 've even filed a complaint with the - against them in which they lied and said they never contacted me. That stopped them from calling and asking for a while ( about a year ) but recently they have been calling me again asking about this guy I have never even heard of. I block the numbers and they create new ones I guess. Just looking for an apology and assurance that they will stop harassing me.
