Angry customer

I'm do disappointed with the driver, I requested a ride for R225 got to the destination I pay the drive cash payment of R230 instead of R225. I got in the home moments later get an email confirming I short paid the driver with R25. I don't understand who in their right mind would request a ride n short pay. This needs to stop. I'm expected to again. Please address this with your drive you will lose business because of them. I use Uber daily and I can not do business with people I don't trust. I'm being made out a *****.
