Account retrieval old premium account

Hi

I'm just beginning to play here again and was trying to access an old account of mine, but I can't seem to retrieve it.

I've noticed that frostwolf has since been ported to MOP from cata and wonder maybe that's part of it?

The account cant have been delete because I'd donated around 100 coins in total and would like to retrieve so I can play on wotlk realms now


My login was temur and had nearly full characters on cata frostwolf, and should have been registered to the same email as this current account.
