The seller may have more of the items to sell and is free to change the listing after you bought your item if they wish.
The listing as it was when you bought the item is still valid.
If you receive only part of what you bought then complete a case in the Resolution for Item Not As Described. No other type of case.

Sellers can defend Item Not Received cases if they can prove that you have received something, even if it is only part of what you expected.
