Bolt using app for ***** and theft

I booked a ride with bolt during my lunch break today. Trip quoted was R50 which is the usual price for this trip I take regularly. Which gets debited from your bank account the moment the lift is confirmed.

Today when the driver picked me up he said his phoned had just died. I had to direct him as to where to go (it's it's same route volt always takes). After I had been dropped off I got a notification to say that the R50 had been reversed and that R77 had now been debited.

This price was never presented to me nor did I accept it. When contacting their customer support they refuse to help and will only give me a R3 credit to their app they wont refund the full R27 which they stole by means of ***** (changing trips after it's been completed).

I am disgusted with this. I know R27 is not alot but it's the principle. I don't want a R3 credit to your app BOLT. I want my FULL R27 back paid into my bank account that you stole.
