payment not returned 7 days later

a friend of mine recently used my card to order food and the food was not delivered. The charge of R184.49 has gone off my account on the 01/10 and was advised that it would be returned. to date the payment has not been returned. i have sent several emails to uber eats and instead i get an automated reaponse and no luck. i am frustrated and desperately need my money back. Uber eats has the worst system when it comes to payments i am appalled and who ever is replying they dont have bother to really investigate instead i get an immediate automated email which is rather insulting. disgusting service
