As far as I know, RAM only comes in GiB sizes. There is some overhead that reduces the amount you see in the OS though. But that complaint is valid for storage devices if you don’t know the units and expect TB/GB on the box to match the numbers in Windows
Pretty sure the commenter above meant that the their RAM was advertised as X GiB but they only got X GB, substitute X with 4/8/16/your amount
