UberEATS Drivers refused to deliver my order and my account was charged!!!!!

On 18 June I ordered food using the App. The delivery time and drivers kept changing. Eventually the 3rd driver asked me to confirm my address. I did. I asked him why the delivery time kept changing, he rudely responded by saying he's not the cook and I should ask the restaurant. I told him he didn't have to be rude . He told me my order was stupid and he wasn't going to deliver it. I decided to go fetch the food myself and raise the matter with the restaurant. When I arrived I was told my order had left with another driver. I immediately escalated the matter to UberEATS and I told them not to charge my account because I did not get the food. UberEATS eats acknowledged my complaint and promised to investigate and get back to me. They have not done Anything since and they have been ignoring my emails. I've asked for my refund. THEY ARE IGNORING ME. I WANT MY MONEY BACK
