Oh Well is correct. They call random numbers looking for live ones, then sell it. If you call back that seals the deal too to sell it even harder by trying to remove it. They don't even bother using the DNC list as that costs them money. 99.99% of these are scam artists looking for a fast buck! A legit caller will always have a caller ID that says who's calling!
Called at 11:24 AM. Caller ID said Gaithersburg, MD. Since this is in the same county as my home, I answered it. No one on the other end.
Probably a low life scammer.
Just another scammer!! Notice now they are using the City and state hoping that you answer the phone. This number has called 5 times today within 30 minutes. I just stopped answering the phone unless it is someone I know.
