I want my money back

On Saturday afternoon I placed an order through UberEats and the order was accepted by the restaurant as a cash delivery as I did not have sufficient funds in my account. Today UberEats has debited the same amount from my bank account and their reasons are that the delivery was not made and yet I received the order and paid in full. I want my money back as this is unacceptable, you cannot go around charge your customers double. The restaurant can confirm too that the food was never returned back but I received it.
