They have called 3 x today - thanks to the info on here - they are now blocked on my phone - although from what others have said, guess they might try again with another #.
Received numerous calls from this number about extending my car warranty, which I don't have one. When I said that they hung up. I called back and a voice recording had me on hold saying my call is very important to them then they hung up. I've asked to be taken off their phone list and I continue to receive calls from them.
