So they emailed you? Reality Based Group is a legitimate mystery shopping company. I'm asking questions because scam artists often use the names of legitimate companies. It makes their little cons easier because the recipient can find a real company with that name.
Here is what you need to watch for before signing up:
1. Do they ask for all your contact details via email? The legitimate company will have you register via their website. You will provide all your information, including SSN on a secure site.
2. Are they going to pay you an inordinate amount of money ($200 per assignment) and pay before you complete the assignment? These scream scam because most assignments pay between $5 and $15 and are never, ever, paid in advance. As independent contractors we are vendors and most vendors are paid once a month.
I've never heard of the person you mention, but that alone doesn't mean she is not a real employee of RBG. I did notice you refer to her as Mrs. McClain. In my experience neither shoppers or schedulers are in the habit of using Mr., Ms., or Mrs. in their correspondence. However, scammers located in places like Nigeria always use a title.
Equal rights for others does not mean fewer rights for you. It's not pie.
