I have been plagued by these people, they keep calling me with my "last" opportunity to renew the warranty on my vehicle. I've pressed "7" as they say to put me on their do not call list, but obviously they have not got the message. I've gotten 2 in the last hour. Don't waste your time answering.....
This same this has happened to me with multiple numbers and it turns out to always be a car warranty auto-dialer. I have been registered on the DNCL for over 10 years. Someone needs to deal with the real problem and keep these companies from auto-dialing. When you pick it up, the system doesn't even register. it just hangs on the line for 10 seconds and then hangs up on you.
