I too got the exact same number about the same job. Once I texted back asking about how to establish trust before I started the work then they stopped texting me. Total scam. At first it asked "how am I guaranteed pay?" Response was "you surely will get paid." Oh...sure...ok. Besides it was advertised 3 hours work a week and get paid $400. If that's 3 hours a day then that's $19 an hour. Sound too good to be true? Then IT IS.

Did not leave a message. When I called it back, recording said this number has been disconnected.

Said they had a job for me, posting ads on craigslist of all things. I inquired a bit, did not reveal anything informative. Almost immediately they started giving me orders about what to do on my CPU. I asked them what part of SD (San Diego) they were in. They respond California. I said I asked for part of SD. They respond los angeles. I said that was a different city entirely. They said they were in Los Angeles and mentioned I would be paid through Western Union. Dead give away there.
