2x UberEats orders that never arrived

I ordered KFC on UberEats on Friday, 6 Sept 2024, the food for R139.10 never arrived. I received a call to check my App, the driver is trying to reach me. On the App there was message from a driver saying, "I am here". I asked where is here and informed him to buzz my house number on the intercom. That never happened, the driver did not buzz my number like all other drivers do when they deliver. On Sunday, I made another order, again that order of R420.50 never arrived. I went to KFC Olivedale to complain. I was told the driver came to pick up the order, my question is where did the driver take the food because it never arrived at my door as stated on UberEats. I contacted UberEats and they told me about the 8 mins rule, which I believe is a *******. I have lost R559.60 based some 8 mins story that does not even add up, because he never arrived at my door to deliver. His message "I am here" where was he because he was not outside my door because he never buzz my house number. I requested my refund to which I was told about I will not get because of this 8 minutes ruse, that their drivers is now exploiting to take customers food for themselves. R550 is lot of money UberEats, shame on you that you are now robbing your customers off their hard earned money that trust that you will deliver, whereas you and your drivers are not ****ming customers. This is disappointing and shameful, you rob your own customers, disgusting. Anyone using your services must be aware that chances of being ****** money and food is high with you lot. I want my refund of R559.60 that I paid for food that never arrived.
