I recently had my first experience with this MSC and I'm torn on how I feel about them. My shops were completed this month so I can't comment yet on whether I'm being paid on time.
However, I will say that my concerns stem mostly around communication. I had some initial scheduling bumps with them that had to be ironed out as they randomly assigned shops to me after I'd replied to an auto email indicating my interest. I didn't consent to sign up for the shops and only expressed interest as I said I had to check my work schedule, but a few days later, I had 20+ shops in my queue! Needless to say, that one made me a little anxious about what the future was to hold. However, I worked it out with the scheduler and I moved on.
The next issue occurred when they wanted me to consider taking a job that would've required a substantial time and travel commitment. They tried negotiating with me, we went back and forth, but ultimately we couldn't come to an arrangement as they weren't understanding the cost and commitment on my part. I was fine with this, moved on, and thanked them for the opportunity. However, the same day this occurred, there was a shop I had to cancel due to an unexpected conflict I couldn't negate on. I profusely apologized, asked to reschedule for any day/time that worked for them, and the scheduler indicated it wasn't feasible. I then see the assignment post an hour later with a large bonus tied to it within the time frame I'd inquired about. What the heck?! Why pay someone a giant bonus when I could've taken it at the original base pay with no other expectations? I guess what also irked me was that they were willing to pay such a large bonus on a shop that was 5 minutes away from me, but wouldn't work with me on a shop that was 2+ hours away.
Oh well... I'm not going to let this eat me up. I've just learned to be a bit more cautious in how I communicate with their schedulers and ensure that my emails can't be misinterpreted in any way. I don't want to make this out to sound too negative as the shops themselves worked out fine and I didn't have issues with the instructions or completing the online surveys. For any new shoppers out there, I will say that they have some easier assignments so for anyone just starting out, you could grab some shops that aren't too difficult and will help ease you into mystery shopping.
Thanks for letting me add my commentary!
