I got the same like Bill. When I pick up the phone , say Yes or Hello, no one say a word. I hang up and dialed back, an answering machine keep saying this number is not available ,please try again. I keep dial back for few hours, got the same answer.

They called yesterday its some comsumer reports place. I asked them to remove my # and they called while I was out today so I couldn't yell at them

These people are a pain and once you question them, they hang up. I've advised them that they have called 4-5 times a day and they then state, it wasn't them.
