Uber’s lack of assistance on being overcharged

Although I’m a regular Uber user and have always been satisfied with their services, I have recently been overcharged with more than R500 on a ride and am receiving no valuable assistance from the Uber customer services. When I booked the trip, the cost shown was R49. After completing the trip, I checked my trip history on the app and found that i had been charged R584,49. This took place on the 2nd of December at 9:30 am and I contacted Uber’s customer services that same day. They told me that due to it being such a large sum of money, i would have to wait to receive a call from their “specialised team” within the next 6 business hours. This never happened and I’ve contaced customer services multiple times thereafter to follow up, but I am told the same story every time with no call from the specialised team occurring. It is now the 7th of December and I am have still waiting for communication from their side after attempting to get it sorted out multiple times and not receiving any of my money back. I am incredibly frustrated and very disappointed with their dissatisfactory service.
