UberEats seGat

This service is very poor I am so angry and frustrated as they just cheat us of our hard earned money even worse during the Corona Pandemic, I ordered my foor yesterday around 5pm and by 6.30 pm the app notifies me that my food had been delivered. I called KFC and they informed me that my order had not been collected yet I can come and collect the order. Drove to the store upon arrival I was told the uber driver by the name of Rajabu collected the order to deliver, I called the driver to know his location and the phone number he left in store was invalid so I purchase the same meal for my family again. . Went on the app and followed the help guide and laid my issue. This morning I get a response that I will not get my refund due to the previous refunds Ive had and which is not true so at the end of the day I have spend R600 for a KFC meal. How does one go about taking action against such?
