Pathetic services from UberEats - Charged for an order I did not receive

I placed an order with UberEats on the the 26th of April at around 11am - 11:30 am so my food would be delivered for lunch. At 12:06 I received a notification on the UbearEats app saying the driver will be arriving soon, at 12:09 I received a notification saying the driver has arrived, I went to the gate and no one was there ( keep in mind there are witnesses as security is stationed at the gate as well as there is a camera at the gate) I messaged the driver on the UbearEats chat to ask if he is at the correct address as I don't see him at the gate , he did not respond , I then received a notification saying if I do not communicate with the delivery person my order will be cancelled so I messaged again and again no response at this point in time i was very confused at the tracker on UberEats was also showing that the driver is now 2 mins away ( 12:16) I messaged again and still no response and then I received the notification that my order has been cancelled but no delivery person had come to the gate ( please note my company has a huge sign on the gate with the address which is impossible to miss, i was also waiting at thr gate as well as security and no one had come) I then logged a complaint with UberEats because i was charged for an order that was not delivered to the correct address, i tried communicating with the driver and received no response , the tracker ssid the driver had arrived then said his 2 mins away. Keep in mind I have ordered from UberEats and Mr D prior to this to this address and there were no issues so I was very disappointed as I was still charged for something that was not my fault. I then logged a complaint with UberEats and it was a constant back and forth, I presented them with screenshots and I was told I cannot be helped as the delivery person could not get a hold of me yet I contacted the delivery person and received no response.
