Purchasing Game Currency


I’ve found out that Razer Gold is now selling Eternal Orbs for Diablo Immortal. It seems it is restricted with some regions and fortunately I’m from one of them, Turkey. Before linking my battle.net account there and making any purchases, I just wanted to be sure if this is legitimate and safe.

I’ve contacted game masters and also created ticket but they told me that they don’t know about it and I should ask in forums instead.

So, does anyone know if I’m allowed to do that?

Thanks in advance.
