Frustrated

I am so frustrated with uber eats. They are not getting back to me regarding my complaint. I placed an order with them today for a total of R177. 80. I have myself and my husbands accounts saved on the app. The payment was erroneously automatically charged on my husbands account. I thought it was a cash transaction since i was not prompted to select payment methods. So when the delivery guy, his name is Wahabu, i gave him R200 for the whole amount of the order including a R20 tip. He did not say anything and took the whole amount. I was oblivious to the fact that the money was already charged. I need my money back. I tried complaining to them on the app but i have not receieved a reponse. I can never tip someone more than the actual order amount. Thats insane. This is really frustrating because now i paid double for my order and no one cares
