Unstable Connection ea fc

I cannot properly play EA FC because every game I lag.
I have tried every possible solution. I followed EA Support steps. I watched YouTube tutorials. I used ChatGPT suggestions. I installed, repaired, and used Cloudflare WARP. Nothing stops the lag.
Even with a ping of 17 ms, gameplay is laggy from the start of every match.
Other online games like Fortnite run fine on my connection. This proves the problem is not on my end.
I paid for EA FC to play the game, not to troubleshoot its network issues.
I have spent hours trying to fix this. It is unfair that the game does not work properly despite my best efforts.
That is why I demand a refund.
Please respond and resolve this.
