Charged for food which driver took

I am a very very frequent customer on uber eats and today i will say that i had one of the worst experiences. On the 23/01/2023 at 15:00 i ordered via uber eats. I used cash method to make payment. I request- or rather left a note that change be brough upon delivery. My uber deliverer gets here and i asked if he brought change. He then advised that he did not bring change and told me to go make change. He then says that he will wait while i go and make change. When i come back from making change. He has left and canceled my order, however, stating that i am still to be billed for my order. So i try to get a hold of ubereats without luck. I then request for the same order at the same restuarant. the new uber deliverer advised that i am being charged double. As i did not pay for my previous order, I was fuming, as you can imagine, as the reason payment was not made is because the driver left and canceled my order. The new driver assisted where he can. And with many complaints via the uber app, i am yet to be assisted. There is still an outstanding balance, which i cannot understand why i am liable for as the Ubereats driver, if i may say basically provide THE WORST service delivery and he should therefore be liable for that order. I made payment for the new order on the app, as i feel that one was delivered, and the driver still tried to assist. I am FUMING regarding the service of uber eats aswell as no one has tried to contact or ever say we are sorting out your complaint. In fact i am sitting in limbo hoping and waiting for assistance. I am waiting for uber to get ahold of me. This is not service that i expect from such a huge company such as Uber eats
