Ubereats drivers eating my food and I don't get any help from ubereats wheb reporting, not even a refund has been issued.

I have had many issues when ordering through ubereats and there's no kind of assistance, the chat bot is not helpful at all. Yesterday my order was not delivered and I can't get a refund. I reported the issue but it's over 12hrs I've gotten no response and this is not the first time this is happening. The driver ran around circles around my place until he confirmed that he delivered. His number was going straight to voicemail. I had order from KFC Mount edgecombe caltex an order that amounted to R188. You telling me I lost R188 for nothing? How does a driver confirm delivery without me giving the pin because this thing has a pin that you must give the driver. Last time samething happened in april and till today I never got a refund for R133 that I had ordered with. These drivers are enjoying tasty supers with my money. I want a resolve to this because I can't be losing money over a non functional app. If this is another **** that the foreign people have brought to our country then we are geading to the wall and people will cry loud and say South Africans are xenophobic, I'm saying this because all the drivers that have done this are our foreign brothers whom I have respect for but this kind of behaviour is unacceptable. I'm tired of the drivers from ubereats and the kfc in mountedgecombe caltex. All these cases happens when I'm ordering in this same place.
