This number has called my home several times and always when I pick up there is "dead air". The last time they called, I used the code *67(caller ID Block) and called them back. The phone instantly picked up and there was a recording that said: "Push any number to be put on the do not call list". This message just kept repeating. I suspect that this is one of those "data mining" companies that ignore the law and searches for "live" phone numbers that can be sold to telemarketers.
This is a scam operation to sell over-priced extended warranties for cars and trucks.
They are trolling the phone lines looking for a few bucks from the few who just can't say no. This is a faked/spoofed number that just goes back to a recording that offers to allow you to put yourself on their Do Not Call List, which doesn't work (surprise, surprise!) since they are still calling me after more than two weeks.
I hope they starve to death in the dark from lack of funds. I certainly won't be putting any of MY money in their hands.
