Cant get authentication code or email. Please help

So I haven't played in a few months, and during my break from OSRS my phone broke. All my apps and stuff was transferred over to my new phone, but for some reason my google authenticator "account" hasn't. I dont believe that i made an account for it or used a gmail account when i registered it with my OSRS account..(is that possible?). Also, the email that i had the OSRS account registered with was deleted because I haven't logged onto it in over a year and it was a crappy website. So i cant disconnect the authenticator or get onto the account. I dont want to try to recover the account just yet because i bought the account here over a year ago and i dont want them to look into it and possibly ban it.. So im in a bit of a pickle. Does anyone know how i may be able to get my old authenticator account onto my new iphone?

Any help would be much appreciated. Would also throw some mills to whoever helps me get back onto my account.

Thanks for reading
