They have called me numerous times, even after I have asked them to no longer call. I suggest making sure you answer and get on the phone with manager. They are looking for your to extend your car warranty. They are extremely rude will hang up on you when you ask to speak to manager about getting off the list.

Called hung up

Another whack a mole number. Blocking and moving on.

Didn't answer the call and no message left.  Called the number back and it was an automatic message that said "If you would like to be removed from this list, press 1."  Pressed 1 then, "We apologize for the inconvenience.  Please allow 48 hours for it to update."
In which case, just call the number back and get removed from the list.  I'm going to add it as a contact and if I receive another message after a couple days, I'll add to this but here's hoping.

Here's a good one. Didn't answer the call but it was ringing on both mine and my wife's phones at the exact same time. That's never happened before.
