Pretty much the same situation as most of the people here. I got a call from the number, answered it said hello but no one replied, hung up, tried to call back, got a busy signal. I'm not too worried about it, if you Google this phone number, seems like a lot of people have been dealing with this issue with this phone number. It's actually how I found this site.
Computer caller, that sounds very human. I said not interested, but it continued to ask for my information. Beware, robo-callers sounding more human, and not prerecorded. It started call with "Uh, Hi this is Sam" like its human and knows you.
