Uber Eats- Scam

I'm really sick of these jerks. They are constantly getting lost or claiming to deliver when this is not the case.

I ordered something through the McDonald's app, and it says that it has been delivered when it has not. When you try to call McDonald's, I receive the following message:

Because your order was completed by Uber Eats, please contact them at 0800 088 5663.

Then comes the nightmare: I've tried Uber Eats, and every time I explain that the order was placed through McDonald's, they state that they will route me through the appropriate staff and end the chat.

The same thing happens if you call them at their customer support number: 0800 0885663. They claim to be having technical difficulties and are unable to assist me, and they kindly ask me to call back later.

Any suggestions on how I may get my money back?
