The worst app or game ever as far as support is concerned. I purchased a gun for over 2 million coins, then it took another 7 million to start upgrading the gun. I went and equipped another weapon to play the game while i upgraded my new weapon. When my notifications said my upgrades were there. I went back to the upgrade setting only to find equip button missing. The only option it had was the buy now button. Meaning my gun wasnt there. It still shows my upgrades as there.Wrong email to contact
