Uber eats **** service

I paid for my order but it was never delivered. I got a notification that the order has been delivered while i never received. When i followed up I was told the driver called me and waited so i wont get a refund, yet I never received a call. The only missed call i got was from a call centre, i tried to call back but it didn't get through. I have tried several times to either get my food that i paid for or get my refund but completely failed. Uber eats help center is a complete waste of time! I even paid a tip for a meal that never got to me😡
