I documented elsewhere my agonizing email chain with an Ipsos project manager and their woefully unclear/unfollowed guidelines for one of the darkness gas station gigs. Both current programs have similar issues.
I took it on as an exercise in diplomacy instead of my usual pedantic ranting, and it paid off in the long run. Finally got them to admit they had screwed up and received full pay for the shop.
Some things never change: MSCs rarely exercise the same attention to detail they expect from their shoppers.
