account hacked gold lost

Hi I am a new player inn frostmourne server and I lost all my gold just about 15 mins ago on all of my characters please help....

Change your password and enable 2-step https://www.warmane.com/account -> security

Btw are you "new" to warmane or just "new" to frostmourne realm ?

I am new to wow in general just played for 2 months or so. As soon as I realized my account was hacked I immediately changed password and enabled 2 step auth. Its just that the gold I have been farming for all this time was lost. And if it is reversible should I collect the golds from auction house before they reverse it. And how long it's gonna take.

It's not reversible, they're not accountable for any item lost ingame, including gold. Get a better password, enable 2fa as skullatbash said and that's about it.
