(Switch) Cheater leaving at 8:2 and I get d/c credit?

To whoever this might concern (on EA side),

Honestly, putting aside 30 fps performance on Switch (which is a crime on its own)/or lack or crossplay for Rush mode on Switch (it's virtually impossible to get a game, unless you create a premade group), how is it possible that you (EA) cannot fix the issue with people disconnecting when they're losing, and I'm being penalized for that? How does it happen year after year, when sore losers use some sort of trick/cheat or whatever it is and regardless if I'm playing Champions/Rivals or Gauntlet, I get the L?

What happened:

1. I was playing the last 3rd round of Gauntlet.
2. I was winning 8:2.
3. As soon as game finished, I got d/c with the msg "there was an issue with connecting to the EA servers".
4. I reconnect straight away (no issues with my ISP, everything else is working fine) and I get the happy message about "d/c harming other players") and to my get surprise my 8:2 turned into a loss? How is this f******* possible?
5. I don't get any objective credit, even though I would get the "perfect round" for winning all matches in Gauntlet 4 as well as some others.
6. The ID of the person I was playing with is:"FootballSloth14".

What are you going to do to compensate for this ridiculous bad design? Why you don't give a **bleep** at all? This is a s*** show game and if it wasn't for my 14 year old son, I would have never ever bought another EA "FIFA" game. 

I'm honestly so done, not going to spend any minute more on this. Instead I will be happy to write reviews of this game on whatever platform (Steam/Google etc.) I can and give it the lowest possible score, for unplayable multiplayer modes. I'm pretty sure, there's no possibility to review any logs for this game and the response (if any) from the Community Manager will along the lines of "it's not our issue, check the FAQ for correct firewall setup blah blah blah".

I'm not going to buy another FC EA game, I'm just so fed up as nobody cares on the EA side and nothing has improved from multiplayer perspective in last 5-6 years. 

Very disappointed customer.
