I bought an air horn, from wal-mart, in the hunting and fishing department. I answer the call and then blast the suckers when a human picks up the phone.
They pirate these phone numbers - you can register them all you want, but it won't do any good. The phone number you see on your caller ID is a number that does not work and is not registered. The only thing you can do is if you see a long distance number or cell phone number you don't recognize, DON'T ANSWER IT. They've been calling us for a couple of years, but now we get sporadic calls instead of daily. There is nothing you can do about it, other than change your phone number. Nothing.
I too have been receiving these calls. I am also on the do not call this. I followed the promps and when I told the person on the other end that I did not want to receive these calls, he told me to press 3 the next time someone calls, so today I did that, guess what the person on the other line asked me " Are you calling about lowering your interest rates?" and I said "no, I want you to stop calling me." He than just hung up!!! So I guess nothing will work with these rude people.
