Losing connection during games

I keep losing connection during squad battles. Last game I played the final whistle went and I was winning 7-0 and I came up unable to connect and gave me a 3-0 loss ffs. And I was doing evo on 2 players and it didn't count on either of them.  My Internet is fine it's your **bleep** servers. If I keep wasting my time and money trying to challenges which I complete just for your game to disconnect and lose all my progress. I was not even playing an online game ffs. I will just delete the game. This is really annoying me now this has happened several times
