Unfair loss given

I just played a FUT Champs game and won it 6-5. As soon as the final whistle blew and I was going to go back to the home screen I was unfairly kicked out of Ultimate Team, I then tried to rejoin and it kept saying "We are experiencing heavy volume of joiners in Ultimate Team". I then managed to come back into Ultimate Team, only to see I was given a loss for a game I actually won. Surely this is incredibly unfair and is it possible to get that result overturned
