It appears that you didn't get all items described in a Sportscard lot. If Mastro gave you everything they have in the lot that you won, then it would be difficult for them to send you additional items.
If their misrepresentation was serious, it's reasonable for you to ask for a partial refund. If they are unwilling to do this you may have recourse to filing a small claims action.
