Dishonest driver

I am a regular bolt formerly taxify user. On Saturday I had trouble loading my card as method of payment and paid in cash. By my 4th ride I was able to load my card. Human error I paid the driver in cash and received change even though the payment method reflected card. Thus I paid twice for the ride. I contacted the bolt support to be reminded that its my responsibility to check my mode of payment, which I do not object. I do rather think the driver was dishonest as on his app it showed card payment and do not accept cash! Sunday I received a reply that bolt support would contact the driver too date I have not received any further response to my dispute.i am disgusted by the dushonesty and The fact that i have had no further reply. What if i had left something valuable like my purse?
