Ok. I just logged into their website and saw the assignments you are talking about.  I am not sure why you think this is a scam.  Try calling them or contacting them through their facebook page.  Also, on their website on the right hand side of the page, there is a download link with contact information for shoppers.  I am not sure why finding this information is difficult for you and also not sure why your scheduler is not responding, but here is all the information I found on their website.  Good luck.
