3 DIFFERENT ORDERS THAT NEVER ARRIVED- COMPLAINTS AND REFUND HASSLE

On Tuesday 19th of April 2022, I placed an order on Uber Eats. We had load shedding in my area and the app kept on giving me an "Oops, something went wrong error". I placed another order and the app would say the food is on its way but the food never arrived. I checked with the security guards at my complex and there were no drivers from Ubereats that evening. I have been charged for three different orders that never arrived. I did not receive a call or a message from Uber yet I am struggling to get a refund. It seems like this happens to other customers often and it seems like it is the companies money making scheme that makes complaints and refunds such a hassle. I have screen shots to prove that the app was not functioning properly that evening and I had no contact from any of the drivers regarding my orders. I want a REFUND on ALL 3 of my orders. I don't understand why this "advanced" technology company can't make it as easy to complain and get a refund the same way its easy to place an order.
