BAD CUSTOMER SERVICE AND THE MANAGER TOO CAREs LESS ABOUT CUSTOMER MCDONALDS IN UMLAZI STATION!!!

I made an online order of A Jalepeno chicken double with Litchi McFizz and a gremace shake. Upon arrival to collect the order I was told they cant find the order rather they did not receive it, I then provided with the order number , the guy who was assisting me was very rude and said the shake is not available because the machine is broken and the person who is able to fix it went home at 7pm , I then asked then why was it not flagged on the app and he did not have any answers. after waiting and being told to come inside and rudely told to park the car else where as there are other customers too which i find very unproffessional and rude. I went inside and requested to speak to a manager , they called her her surname is Mkhize but she did not bother to show her face , I waited and asked the lady in the front that I need assistance as no one is attending to me and she said they are fixing the issue after 10-15 minutes of waiting she comes back with a phone and said the manager said she cannot refund me I need to call a certain which I took a picture of . No apology nothing just that I am disgusted with the service I received and still went home with an incomplete order as I did not get my Gremace milkshake, as a pregnant woman i was treated unfairly and I would like to take this further and will be writing this on my social media pages and going as far as the ombudsman. I have all the proof needed for this.

I need to be refunded the money for the gremace shake.
