Character XP maxed out by hacker on PC - request for server data reset

Probably there was a problem with EA servers or someone hacked/used an exploit, and now every character on my account (even characters I don't have) has the highest rank, and the biggest amount of XP possible. Now I'm at a disadvantage, because I don't have upgrades I should get through natural progression. I don't have any ways to get them, and all my progression and fun from the game was taken. This happened a few months ago (because I couldn't contact you), if you could find and rewind my progression to the moment before I got all this XP I would be very glad. If you can't find this moment, then please reset all my data in the game.

The game is called Plants vs. Zombies™ Garden Warfare 2. My platform is PC (Steam).

(Note: I already tried Live Chat, but the advisor told me they couldn't help me with this. Please help me reset just the GW2 multiplayer server data, just like in other solved threads).
