UBER *****ING MONEY!!!!!!!!!!!!!!! UNAUTHORISED TRANSACTION!!!!

I requested an Uber ride on the early morning of 30th December to the airport, an amount of about R296 was immediately deducted from account but no driver arrived, the app kept saying, ‘No driver available.’ I’ve messaged the HELP support on the app and they are apparently looking into it! Looking into what!!!!???? I want my refund ASAP!!!! Such an inconvenience!!!!!!!!!
