Account password reseted

Hello!

I have 2 accounts in here and both of them are premium accounts. Now i started playing again and both accounts passwords were reseted and i don't understand why? I was able to recover other account but other one i couldn't since it has really old email and even the email doesn't exist anymore or atleast i have no chanche to log into that email since i havent been using it for few years now. So what i need to do now? Can someone contact me and i can provide all the infromation what needed.
