Missing order

On Friday I purchased Mac feast medium meal worth R113 and a burger only for R91 and upon delivery the burger only was missing, I immediately called the driver and he said that that's what the store gave him, I logged a query with support and after run around they said my issue is resolved where they refunded me R38, like how?? Till to date the has been no response from Twitter support and the app as they say the query is closed. I am disgusted at their service so far. I will never use any of the Uber services if this is not fixed accordingly.
