Vehicle Services Dept Rude and harassing response to phone call requesting removal of my 89 year father from their mailing list. Plano Texas

My 89-year-old father continues to receive phone calls and letter from Vehicle Services Department asking him to extend warrenty on car. He has told them no serveral times. 

Today, I called the company and asked firmly but politely to have his name removed from their mailing and calling list. The representative then noted that the car's warrenty had expired and told me most repairs for a car that age would cost $3000. He then asked who would pay for these charges if the warrenty was not renewed in a hostile and acusitory manner. 

I explained to him that I viewed his response and the numerous phone calls and letters to my 89-year-old father as harassment. 

I also reminded him that I had requested my Dad's name be removed from the company's list. He said he had done that but again asked who would pay for the repair cost for the car. I told him that I didn't feel that information was any of his business. 

He replied that it was indeed his business since he was a warrenty specialist. At this point he was shouting over the phone at me. I hung up.

I am a fully competent adult and was extremely distressed by such rude and harrassing behavior. I am appalled to think that representatives of this company have been talking with my Dad most likely in a similar manner. 

I see other compaints have been posted about Vehicle Services Deptartment and hope my voice will lend weight to these complaints.
