Any way to recover lost acc ?

I had an acc on release that I used to play on and it had good units and a few limited skins or what not. I recently got the game from mobile but deleted the game from my PC (that I used to play it on) some time before. I tried logging into the email I think I linked the old account to but it wasn’t that, I tried others and same result, even got a new Apple ID to download the other client to use sunborn ID but still same result. Can MICA help me recover my acc or is it completely lost now ?
