Order never arrived but I was charged

I placed an order yesterday at around 15:50 on the uber app from Pure Oasis Dining. The purchase amounted to R450 in total including the delivery fee and the charge was made to my bank account. The estimated arrival time was 16:30 to 17:00 and there was no communication thereafter as to why the delivery was delayed. The app kept saying I should request and update from the restaurant or call them which I did and the number could not go through. I then received a WhatsApp message from Ben from the uber eats support telling me that there is an issue with the app at the moment which was true because the map was not working properly and the arrival times didn't change, there I was given a link in order to track the order which also didn't make a difference because it was still the same. After some time I decided to go back to the Uber app to check if there was at least a change only to find out that the order was delivered but there was no communication whatsoever with me. My Uber app was then refreshed and it looked like I have never used it and I am a new user. I would really appreciate it if they can refund me the money that was deducted from my bank account and deal with the issue because so far I haven't received any communication from the customer service.
