Problem with Diablo II key

Hi,
i have bought the Diablo II - LoD key from G2A.
In the description was reported that the base game + expansion was present in the package. When i redeemed my code, in my blizard account, Diablo II - LoD was added but base Game no. So, i can’t install Diablo II and can’t play with LoD because i haven’t the base game. Can i do something or i was scammed?

Hi, marefano! o/

In this case I would contact the seller. DII and LoD were always sold as separated keys, so you should have received two keys if what you purchased was both the base game and the expansion.
