Locking up during "PvP"

It’s not bad enough that the match making is crap, or during “PvP” events I seem to only fight people leveled well above me but this locking up during battles is so damn annoying. You guys charge gems to refill chances so people spend money to buy more, you should make sure the game works. Spending gems and losing battles because you lock up every other battle is ridiculous and should have been fixed months ago. If these weren’t issues and they got fixed instead of doing nothing maybe I would actually buy stuff and support the game.
