So this Doug Martin is running over a couple of numbers. 408-418-5683 out of San Jose also has a Doug Martin inquiring about credit cards.....

Same here. About a FREE security system.

To prove it is a valid number so they can turn around and sell it on call lists.

Same as "WhatsAmattau". I clicked through to the "please have a rep call me" and heard that that would happen "within 20 minutes". I planed to vigorously harass the sales rep when he/she calls including threatening legal action.
... that was a almost two hours ago and no callback. If these people get a positive response and then don't follow up on it, why are they calling in the first place??

Got the Call said they had sent me some confidental items in the mail about my credit card and they were doing a follow up i told them i do not have a credit nor does anyone in my house hold that is when i found out that it was a recording so i hung up Caller id said LRC

The question was rhetorical.

Recording offered a promotion on a G.E home security system.

It said in a recording:  the FBI reports that there are xxx break ins - I hung up the phone. I usually don't answer these if I don't recognize the number, but it caught me off guard.  I hate that when that happens

This caller said his name was Doug Martin and he was calling about my credit card. They sent some offers and this was a follow up call. I hung up. No thanks, don't trust any one with credit card info.

Got a voice mail (recording) asking seniors to press 1 for information about a "free medical alert device".

or press 9 to be removed from this list.
