Lying info from Uber Eats driver and useless app for helping customer.

Good day I placed order for lunch today in Edenvale. On my delivery address I stated the company name and address. We have huge signage outside to show where we are and can't be missed. Was waiting for delivery, busy with a meeting in the meantime while waiting. When I saw there was note that my food has been delivered and picture of the company delivered to. When I walked next door to find out they advise the delivery bike stopped in front of their shop, took picture of their shop and left without any notice or walking in to ask for me (which in any case is the wrong company if he looks at the delivery address). When I tried to phone the delivery guy from the app there was no response so can ask him what is happening. Trying to get hold of Uber Eats for assistance with no luck as they have no customer service number and can only ask for help on the app that I find very time consuming as they only reply to hours or days later. My help complaint was put in on the app after 12:30 today and I am still waiting for my food or refund for the food I never received, but with no luck. Now I am asking question one how the delivery guy dropped off my food without my pin that needs to be given, question two food was not delivered at all so where's the food, question three I phoned the takeaway shop and all they said sorry you need to speak to Uber Eats, what is impossible as they don't assist immediately. Then I get a notification that the drive wants to confirm his tip, tip for what lying and free food that he did not pay for and took where? Cost me double today as I then needed to go to the shop around the corner just to get something to eat for the day.

Not my first time having issue with Uber Eats, before the guy just refused to delivery my food, got phone call from take away shop I need to collect as the delivery guy not going to deliver. With huge fight they delivered. Then they deliver wrong food or less food then ordered.

Must I drive to the Head Office and see if they will reply or resolve customer issue.

Waiting to see when I will get my money back or if the food will rock up at some stage, not that I want it now. Will take my refund and see what Uber Eats will do about another unhappy customer.
