Report bug of this game

I am very dissapointed by this game in such days due to many problem i cannot get rewards and also cant redeem codes on my account "calmdownbruh”today i was playing game and i lost not due to my fault but of some biasness toward the opponent because he do purchase and i dont he had better players so the game give him more chance to score goals in vs attack i also have a screenshot i was able to rankup by this win but not due to the game cheating .it dosent happend first time with me but also many times before but i ignored.
