(I am not going to criticize Market Force. I had a good experience with them while it lasted. My post is meant to inform other MF shoppers about my experience.)
I performed many shops for Market Force. Last month I performed 30+ fast food shops. During my 3 years at Market Force, I had never performed more than 5-10 shops per month for them, and I almost always avoided their fast food shops.
Back to last month. I reported everything that I saw and overheard, and all of my timings and observations were documented. During that month, I gave very poor marks to 8 of the arches shops that I visited. The day before my deactivation, I gave an arches shop the lowest grade possible, because I had to wait at the walk-in counter more than 7 minutes.
I was deactivated, by having the select new shops link removed from my shopper page, but was told that they would appreciate it if I would complete the remaining FF shops that I had already scheduled with them (12 shops in total). I declined their offer to complete their shops.
I found it puzzling that I could be deactivated but still be allowed to complete future shops for all of their FF clients (I had future shops booked with all of the FF clients).
As an IC, I accept that the client can do this. It isn't fun, but I accepted it and went shopping for some clothes for myself, which allowed me to feel good again.
