Kicked out for no reason

I just got kicked out of a fut champs game for “connectivity issues,” even though my wifi is working just fine, on literally EVERY OTHER MOTHER**bleep**ING game, website, app, and device I’ve used, and normally its fine but there’s an objective where i specifically have to play every single champs finals game for a reward, so please give me my game back. I was kicked out instantly so I feel it is ridiculous for me to miss out on the rewards because of this. This was my fifth game, and now that I think about it, it was my opponent that disconnected first, then suddenly my game froze, then sent me to the main menu.
