Appalling Service - No goods received

I went to McDonald's Rissik street 24th of January 2018 around 20:30.

Ordered their combo of R175 and a McFeast meal and extra mayo. Firstly, the people at the back were very rude and secondly, when I got home, I checked my food and realised that they never even put inn my Mcfeast Meal. I paid around R70 for a meal and they never GAVE IT TO ME. THIS IS SERIOUSLY MESSED UP BECAUSE ONE, I PAID FOR IT AND TWO, I COULDN'T HAVE A MEAL BECAUSE OBVIOUSLY THE MEALS WERE SHORT AND I HAVE TO OFFER MY MEAL TO MY SON.

I will never ever buy at McDonald's again and I promise if they do not rectify this problem, I swear i will go onto social media and make a huge noise and get people to boycott McDonalds
