decided to weigh in on this (been absent for a while)...
i have no dog in this fight and while i'm not an apologist/spokesman, for either ipsos or their scheduling company/team (summit scheduling) both entities are nothing but...the best, top-of-the-line companies to work with.
summit's schedulers are communicative and pro-active, their editing team the same way and they treat us in the trenches with respect and value the work we do.
if ipsos chooses to do their own scheduling for a special/one-off project, etc i really can't comment on that other than sometimes it's best to stick with what you do best and not get involved with things that others can do better?
is it not incumbent to read the guidelines/instructions, etc for each and every assignment and not make assumptions that they will be the same (even day-by-day) or that its a one size fits all ?
if guidelines/instructions are to call before going to ensure the biz is still open, etc. and you didn't/can't or there is no answer or an answering machine then you didn't follow those guidelines/instructions you shouldn't be paid if the biz is no longer there.
