Double charged

I requested a trip 21/06/2020 and my payment method was via card. My trip was about less than 5km. The driver called me and asked me to pay cash for the trip. He picked me up and I paid him R35.00 when I got off the car to get into the house and I receive and email and it’s Bolt R48.00 debited off my card. I’ve been back and forth and still no joy regarding my refund. It’s been a challenge for so long now. ****ty ****py and some unprofessional drivers. You have ********* driving us which puts our lives at risk every time we get into one of your vehicles. You have some people signing up to become drivers and then it’s another person who picks you up only to find out they using other peoples accounts to sign in so one day you may not even get to where you going because you put your life at risk with unknown drivers to Bolt. Serious investigations need to go on, your service is just unsafe. I used Uber before and they so professional about everything and I think it’s time to switch back, my life matters more than a few cents of savings.
