Vehicle service department Repeated phone calls and mailings Plano Texas

 We receive letter threatening that if we do not call our auto warranty will expire. They say we own a 2013 Corvette, we are a Ford family and have never owned a Chevy Corvette, When they call they tell us they will remove us from their mailings and phone calls then they try to get us to register our current vehicle with them, our vehicles all have extended warranties And we tell them no thank you but they keep insisting when we finally get rude and I have even told them to go to He!! They still call!!!
