Has anyone done mystery shops for this company and/or have knowledge of them?

I have an upcoming shop for them and emailed two different emails associated with the company without any response. I am wondering of it's still a good company. I appreciate any feedback/input!!

No, but they use the same platform. ISS is like a main place that combines different companies to my knowledge.

It's Mystery shopper services/business evaluation services

Woah, sorry for the large text :-)
