General Warranty Services harassing calls Internet

This company called my DNC listed cell phone 10 times in one day regarding an auto warranty and I have the documented proof in my cell phone bill (very fishy, because I don't have a car and I'm not a licensed driver.) Harassment continued every day for about 3 months, even after speaking to employees, averaging about 2-4 calls a day. I was told on several occasions that I will be removed from the list. One day I just had it and called to give them a piece of my mind. Now I have recorded this call with one extremely rude employee calling himself Brian, cursing at me and telling me he doesn't have to do anything I ask. I tried to call back to get a supervisor and inform them of this, but I keep getting nowhere with them. Would not trust this company at all.
