Edit: MasterCard can also help you get things resolved if no one is being helpful. It used to be against the rules for a merchant to charge you extra to use your card under a certain dollar amount, or to have a minimum purchase amount to use your card. Meaning they would say you couldn't use your card to buy a $1 pack of gum. You could report them to Visa and MasterCard and both went out of their way to investigate and would yank merchant accounts if the merchant refused to comply. Things did change after the big class action lawsuit, but that was a suit involving merchants, not card issuers.
