What can I do if EA disconnect me

I played all 15 champs games and got disconnected from 3 (by EA not my wifi - which I’m sure of) in one game, the opponent had already left, then 5 seconds later it says that EA can’t connect me to their servers - so it counted as me playing but didn’t go the the objective, and all 3 games (even though i was winning or had won) counted as losses so I got much worse rewards
