What the OP wanted was more than some instrument instruction. He wanted the required three hours in preparation for the check ride, and the instructor's signature that he was ready for the check ride. A thorough review of the logbook was certainly warranted, especially since some of the "instrument instruction" was not from an "authorized instructor". Perhaps the CFII was more critical than he needed to be, but in view of all the factors, maybe not. And, he was a newly-minted CFII, and understandably cautious.
