The similar situation happened to me with Secret Shopping Cart. They e-mailed me about setting up the date to work my first job. It was all through instant message with a guy named Peter (peter: email@example.com) They told me I would be reimbursed for the shipping and handling charges up front so I wasn't out any money, AND on top of it I would be paid $12 an hour. It took me THREE HOURS to fill out all my info on the 10 websites of free trials on the excel sheet they provided me, so I was glad I was going to be paid $36. He said it had to be reviewed before I would be paid.
I had to keep track of all the trials so my credit card wouldn't be charged for all of them. I canceled all of them in the time of each trial ending. I had to return a couple of the trials back to the company to prevent being charged which came out to about $11.00. I e-mailed Secret Shopping Cart, asking to be reimbursed for that shipping and then be paid (it had been 30 days now). I heard nothing.
AND THEN I looked at my credit card statement and there was a couple of charges that I had no idea where it came from! Calling both companies where the charges came from, both sadi they were "extra" things I signed up for when I did the free trial (even thought I KNOW I was never told about it. One company refunded the money, one didn't so I had to dispute it to my credit card company and they refunded it.
I have tried to Call, e-mail, instant message: NOTHING!
SECRET SHOPPING CART IS A SCAM!
