Burger King Montana and its employees that don't check the food if it's correct before giving it to customer's how pathetic

Burger King Montana and its poor service. I bought 5 Burger meals only for them to give me four meals and when I called to inform them they don't pick up calls and it's my second encounter with them and the irritating thing is as if they are proud of the employees work ethic or maybe they train their stuff to be ******* or untrust worthy
