Bad service - McDonald's the Ridge mall

Bad service Lady taken order was not replying while we order. She got it wrong and i had to do it all over. Ordered quaterpounder with cheese med meal. When i get it no coke. I questioned the *********** lady and she says there is not suppose to be a coke. But displayed on the board is a coke and chips with the meal. As well as on google.

I also bought 2 watermelon mcfizz. There was so much gas and it tasted bitter. Not even drinkable.
