Disconnecting from the server

I can't play games for squad battles because it keeps on disconnecting me from the server. I have evolutions to do but I can't do it since it keeps on disconnecting from the server mid game. I don't have any problems with other games. Why does it keep on happening with your games. I can't even play the game casually because it keeps on disconnecting from the server. I don't have any problems for call of duty, just this. I can't do evolutions progression that I paid real money for the fc points because it keeps on disconnecting from the server mid game, it has disconnected 3 games in a row. I need a compensation for this because this isn't right.
