Overcharged

I requested a ride at dobseville mall to braamfisher, little I did not notice that I used card payment as the app as well did not notify me till now I receive an sms after I arrived at home, the time I requested it was charging me R46 so when the driver dropped me off at home I took out R46 cash and paid him not knowing or noticing that I did card payment please bolt must refund me back my money this is unacceptable at all. The driver name Senzo Samkelo Ngubane he drives meroon Kia Rio he's not honest now he's not even picking up my calls. Number plate it's FT32SMGP
