UberEats - Worst customer service EVER

I ordered dinner last night at 17:41 through the UberEats app. I also paid extra for urgent delivery and gave the driver a generous tip. I was advised on the app that Burger King was busy preparing my order. I've got a 6 year old child who was looking forward to her food and the supposed delivery was pending. At 19:30 when my food had still not arrived I phoned the driver directly. First he advised me that it was the wrong number. After that I phoned him again and he told me that he's not working that night. I phoned Burger King directly and they advised me that no one was there to collect my order yet. Eventually I had to drive to the Key West shopping centre to fetch the food myself at 20:00. On my way home I got a telephone call from UberEats. It was an overseas number. He told me that I will be charged for the food but not the delivery. Obviously being upset I asked him what is going on with their system as they should've assigned another driver for delivery. He then put the phone down in my ear. I will NEVER use UberEats again. This is by far the worst service I've ever experienced and really expected more from UberEats. I am completely disgusted and would advise people to stay away from UberEats.
