Mr delivery poor service

This is now the 2nd time we have had an unpleasant exerience with Mr delivery. The first time ordered a strawberry berry milkshake from Burger King Centurion Lifestyle received a milkshake that was pure syrup no ice cream or anything. Milkshake isnt sealed in a bake the mr delivery courier could have chhecked. Today ordered a mozarella cheese*****s burger. When you go to Burger king itself the burger is R79 on mr Delivery R97 and R9 delivery so for that I expect the correct items. Received a burger here no mozarella stick only a patty 2 slices of onion. Really mr delivery should either check the orders. I mean why make use of mr delivery when at the end of the day you need to drive to burger king self and get it sorted.
