I have asked the associates to stop calling my number repeatedly over my expired warranty. They go so far as to call me twice in one day. I've had enough and I am going to consult an attorney about this, I will pull my phone usage to show how much they have called.
There are several of these "car warranty" businesses around, so there are several numbers that will call you.
And some of them even send letters in the US Mail.
They continue to call, even after i request to be removed from their calling list (my number is also on the do not call registry). Once i got them on the phone, the agent hung up on me, mid sentence when i requested they stop calling me.
