Reverse Cross Progression?

Cross progression was pretty bad for me and I am wondering if there is any way I could undo the cross progression? I would have rather had my 2 accounts stay separate to be honest, I lost every stat and badge I ever earned on pc and didn’t even have a say because they were under the same EA Id. Sucks because I don’t even get my S18 ranked rewards or badges, I just never received them for some reason. All stats for characters and badges for those characters I never had before have vanished, now all my wins and kills are just gone, everything that made up my pc account except skins has disappeared. I was really looking forward to cross progression and now I don’t know if I’ll ever play again. I know some people would probably say to just get the stats again, but in the end it took way more time and effort than I will ever get back and now it’s all pointless. If the accounts can’t be unmerged then that’s * but I will probably get over it. If I can’t receive help with that issue can someone atleast help me receive my s18 ranked rewards because I didn’t even get those, sorry if my grammar is bad thanks.
