You can feel free to write to support about this k1tb, as dave1311 said.

Also take note of how many videos you watched so that the agents can compare that with what's archived in the system.

But please know that sometimes it can actually take some time for a booster to be added. Videos just like offers have to be verified (Rather the fact that you watched said video has to be verified), and this can slow down the process. I often have this "issue" when watching videos through my home wi-fi (I've actually talked as to how bad my home network is in a different thread), and sometimes I get the boosters a few minutes later. But to be honest I always get them eventually.
