Got a call from this number, after almost falling for his fake mystery shopping job that I found through craigslist. He wanted to make sure that I had gotten his 2250 dollar check in the mail (which I had, and took to my bank so I could verify the company....it had gone out of business in 2003, there were no funds)
I have found another report of this company pulling the same deal, saying they want people to be their mystery shoppers, for Walmart and Western Union, sending a check, only to have the check be a fake. You loose all the money.
BEWARE.
In my case, the caller's name was Allen, and he was "working for" Mystery Evaluation Incorporation.
I have not received a call from 773-455-7792, however, there is guy named Stephen Baker using this phone number to advertise a driver for his wife on craigslist. I communicated by email for a few days with him, up until he said UPS would deliver payment for driving his wife around for 6 hours a week. When I emailed him to let him know the payment did not arrive, I found he updated his ad on craigslist. Obviously, he is not a legitimate employer, so beware!
