Ghost negative balance

In September 2022 I used Bolt for a cash trip which went quite well until I was rating the driver. I noticed that I had a negative balance of R86 which I did not recognise. After playing around in the app I realised that the negative balance was from a trip in May 2022. Why a supposed failed payment has shown up 5 months later is beyond me. I contacted them via the in-app support and got what seemed like an electronic response which died down and has also disappeared. I tried contacting them again last week and have gotten no response.

I am now forced to use cash because of their error which is incredibly inconvenient. I'm not too fond of it when support disappears but are quick to deduct their money, it's deplorable business practice.
