bolt driver changes payment amounts

hi good day,

im sending you this email as i am very livid and unsatisfied with your driver and what he did.

I requested a ride from eersteriver to brackenfell at 12H00pm today

The trip was charged for R197 which I accepted, after waiting more than 5min for him to first get done with his previous trip I proceeded with the driver to my destination. while in the vehicle he asked me if another route he knows of will be quicker I told him i'm not sure and he should check the route the app is giving he said yes he will.

Then he told me he was taking another route. It's quicker I said ok.

After the trip was completed I received a notification from my bank that the driver did a reversal of the R197 and changed it to R257!!

this is unacceptable!!! how does a bolt driver have authorization to reverse an initial payment???

I'm disgusted that bolt allow drivers to change payments. I would like to be assisted immediately because there is no telephone number I can call ?? how is this possible ?
