Purchase products for extra gems ???

This may seem trivial BUT I have purchased products when special gem offers are posted.  I have NOT received my GEMS !!!   I have reported this to TAPJOY, sent all the information, screenshots, and asked for for resolution many times over the course of 10 days  It was like a vicious downward spiral and I NEVER got any resolution.

Has anyone else had this problem?  I would NOT have purchased anything just because it wasn’t for the GEMS offer.
