GAC bug cost me the round!

I was playing Leia VS SLKR and I killed everyone except SLKR, then the game froze down, my buttons dissapeared, auto didn't work, and even after the timer ran out the battle didn't end! So I had to restart the app and the whole SLKR team is there!! I have video proof, and I demand this issue being addressed, and my ranking being credited with a win! This is getting ridiculous, the game play is getting worse and worse. How do I get in touch with costumer support over this issue? I'm not farming DCs and buying passes so I can lose in GAC due to glitches! GAC is the main source of crystal income, so I'm expecting this to be resolved. Like I said I have videos showing the timer at 00:00 and SLKR is just standing there in ultimate form and nothing happens. Fix the game and credit me my win! 

Edit: Nevermind I still WON. Luckily my opponent didn't bother to attack until the last half hour and ran out of time. It was still a super annoying experience!...
