Can't log into my account

hello, i was wondering how far i have to go before i am given the option to log in. i had this game on ios a while back and had an account. i made a lot of progress and i played it a lot. i finally got the money to buy the game during this summer sale on steam and when i opened it there was no option to log in. i made a random name thinking that maybe after i complete the tutorial i would be able to log into my account but there’s no option. it keeps telling me i’m a guest and that i should verify my email. i tried entering it and it told me that email was already being used. i don’t know what to do because i don’t want to lose my progress and i don’t want to keep the random name i made. please help.

You should enter their Discord and message Atmaz. He is the community manager and has been very helpful to me in the past.
