Thank you everyone for your advice.

By "refused" I mean they said that their system didn't show I ever clicked on the York promotion so they won't credit the points to my account.

What I would like to find out is if anyone else clicked on the York Photo clickthrough and got the 5 points or joined and got the points. Since I clicked on multiple York ads (5 points each) and my account doesn't show any of them, I am thinking this is a system issue. If others received any points for the York ad then I'll resign myself to not getting the points.
