Rec'd this call where I work. I get these calls almost everyday from telemarketers. This one I didn't even listen to. They are very annoying because I invariably put a client on hold to answer these harassing calls for nothing! I think our government needs to do something about this. I have kept a log of the numbers. If you call the number back you usually get a msg. that says the number is no longer in service. I've tracked many of these kinds of calls back to warranty renewal telemarketers (scammers). Even AT&T uses telemarketers to harass business owners to upgrade services. They are relentless. They continue to call back even when you tell them to put you on do not call lists! The Federal Trade Commission needs to do something about this. Unbelieveable!
