Disappointed in service

I am very disappointed in the service that i have received from Taxify(Bolt). I took requested a ride yesterday and my payment option is via card payment when arriving at my destination the driver advised he could not end the trip as he was having difficulty with the app. He then advised he will restart hes phone and try again and this is when i got out. Ten minutes later i get an sms notification that R341 has been taken from my bank account which is triple the amount of the ride the driver never ended the ride after i got out he drove off to another location and then only ended the ride. I reported this to taxify immediately the only respond i got was that they will contact the driver and investigate i wasnt provided with any timescale of when my money will be refunded and i still haven't received any feedback yet. I wont advise anyone to save their bank details on the app
