Uber Eats complaint: Food not delivered

On June 16, 10:30 pm, I ordered a meal from the Restaurant Shiso Burger. The order was processed through and the debit was made on my account.
The food did not arrive.
The app did not send any notifications about the ETA or the ation of arrival as is normal.
The driver did not contact me by phone.
My building’s door bell is not working, so I expected the driver to text me once he arrived. This is normal procedure.

I’ve contacted Uber Eats about the issue and they have not agreed to make a refund. They claim the driver tried to contact me and that my notifications of the App were turned off. They fail to produce any proof of what they claim.

I attached a record of the calls for my UK number, which was associated to my Uber Eats account when I ordered and which shows there are no missed calls or messages from the driver (note that I have now changed this to my Swiss number).

I also attach my interaction with Uber Customer Service.
