Bad experience

We ordered milkshake and burgers takeaways for dinner, milkshakes came in a paper coffee cup (which is smaller than the usual) tasted foul, had no cream or topping on it, a few sprinkles and no milkshake syrup on sides. No support from manager. Burgers got mixed up no labeling and mushrooms on a Hawaiian burger NOT ASKED FOR. Quality not in standard anymore. Very disappointed in your food and client service.
