Ubereats Driver *****- No help from support staff

I ordered a R500 meal with a tip from The Dros Stoneridge through Uber Eats for my fiances birthday. A lady driver accepted the order (her name was something along the lines of Tshiphinda), her profile said she was both an uber driver and an ubereats delivery person and had completed over 3k trips. She arrived at the restaurant and parked quite far away, i watched on the app as she sat there for about 5 mins and I presumed she was waiting for the restaurant to wrap up. Suddenly the app said another driver was on his way to collect the order and her profile disappeared. The order was reassigned to about 4 different drivers after that so I called the restaurant and the manager confirmed that the first driver, a lady, had collected the order 30mins ago and he now had 4 other drivers waiting at the store for the same order. I contacted Ubereats support as this experience not only wasted the time and money of 4 other drivers but it completely ruined my fiances birthday. Yes the money was refunded but my worry is that she operates in the area and no responsibility was taken by ubereats to ensure something would be done to stop her from doing this in the future. By the time the manager had confirmed what happened, curfew was in place and it was not possible to order from somewhere else. Despite multiple emails and chats on the support part of the app no reassurance or accountability has been taken by uber to follow up with the driver who essentially stole on purpose and is still operating under their umbrella. There is no way to report or flag her. In these times uber is facing such bad press with how much they pay their drivers and now there is No way to report a driver that is a *****.
