This number called my work AND cell at the exact same time... tried answering on work phone and no one on the other end. Tried calling back from work phone and it rang 7 or 8 times and went to a message saying they were unavailable and to leave a message.
Actually, it works for legit bizs. It's the scammers that ignore the rules. That would include the biz in this thread. Call block is your best bet with the scammers. Of course, spoofing can lead to a lot of blocked numbers.
