UBER EATS CHARGED MY ACCOUNT FOR AN ORDER THAT I DIDN'T PLACE

Uber Eats charged R182 to my credit card for an order that was not placed by me. I have emailed them a number of times, they responded and provided confirmation that I did not place the order and thereafter when I asked for a refund as well as the progress of the situation, they did not respond. I have sent multiple emails to follow up and there has been no response.
