unhappy customer

I booked a trip today , Money was deducted from my bank account and I was not aware of it , so when my trip ended I asked the driver how much and he charged me more than the trip amount ( in cash ) I only realized I was charged twice when I got to work . I did inform Bolt but there has been no response .What I would like to know is don't the driver get a notification when payment is received by card? Now I have paid double for 1 trip and I wanted to be refunded asap . Bolt has till not been in contact with me in this regard
