BAD SERVICE FROM FISHAWAYS N1 CITY

I had a bad service at Fishaways N1 CITY tonight 23 April 2021. I ordered food around 17h45 through Uber Eats, the expected delivery time was 18h25. The time kept on changing and the name of the driver also changed after the first hour of waiting. At 19h05 i phoned and the store manager called Shawn responded. I informed Shawn that i have been waiting for more than an hour for my delivery. He asked for an order number. There was no order number after putting my order through Uber Eats, he said there was nothing that he could do i must phone Uber Eats. I asked for Uber Eats telephone numbers, he said i must check on the Uber Eats app. I told him that the app does not show the contact number, he said there was nothing that he can do when it comes to dealing with third parties. Shawn was very rude, no sense of attempting to assist and went on to tell me how many Uber Orders he was handling. I told Shawn that i was going to report him for his behaviour, he said i can go ahead to report and even said a mocking `have a lovely evening mam`. At 19h25 my order arrived and i asked the drive for the contact number of Uber Eats and he said he does not know the Uber Eats numbers as they communicate via an app and it does not show any contact details. He even demonstrated how they communicate on the app. What recourse does one have for this type of bad service,? I really want to hear from Fishaways Head Office / Famous Brand. It is Shawn this side who is managing the Fishaways food outlet who does not care a bit about the customer`s complaint and there`s Uber Eats remaining uncontactable when there are problems. Advise please what is the recourse. Julia Modise
