Trouble with linked accounts

Not too long ago I purchased a skin on apex through steam but later on I was logged into the wrong ea account and accidently unlinked the account from steam, I didn't know which email was the account and I put the wrong email and now I have just found the correct email to the account, but the problem is my steam is connected to the wrong email that I used and I can't get access to it right now because the email i used is connected to my grandmothers phone and we have different timezones and shes mostly at work. I can show proof of me buying the skin, having both account credentials, both email credentials, basically everything to prove these accounts are mine I just cannot log into the account because it asks for a code to log in and I am no longer in the email. I can log into the email and ea account by tommorow but I still want to know will I be able to get the account unlinked and get the original ea account back linked to my steam.
