Uber Eats, not delivering

After ordering, payment made, the food was not delivered. The amount deducted was approx R550. We have load shedding, the buzzer did not sound, the phone calls did not come through. The driver took a picture of the food balanced precariously on top of the intercom. It would not have balanced there. Ostensibly having waited 8 minutes. Regardless, the food would. Or have balanced there. I do not believe it was left there, I think it was taken by the Uber driver. It is completely unacceptable to be billed without the food being delivered to my doorstep. We live in a country where normal processes are not so. Uber have refused to give a refund. There is no recourse, they have lost a customer, I would rather deal with vendors directly
