I purchased 2 25% XP for 3 days from marketplace. They were both working for about 3 games when I noticed only one was on lobby screen and I was only getting the one 25% bonus at end of game. I bought another 25% today and the same thing happened AGAIN! It was there for a few games and then POOF! GONE! I still have the one 25% with17 hours left. What's up with this and who do I contact to either get my 2 XP bonuses or a refund?
