EA messed up my progress

I've been playing this 5 last days the gauntlet event and wasn't able to win it 3 games in a row until now, I was in my 3rd and last game and was winning 7-1 at the 88th minute and my controller fell to the ground for like 9 seconds and when I picked it up it expelled me out of the game and I just lost for no reason, the amount of hours and making 3 different squads just for nothing, I need help with this because no way I just did all that for nothing, please.
