****med R144 by UberEats driver

I ordered KFC to the amount of R144 (including delivery) on September 14th. When the driver arrived with the food I paid R200 cash (R56 tip). The app now says I still owe R144. This is the 2nd time this is happening. UberEats drivers are ******! I will never use this app again because I'm not willing to donate R144 to Ubereats.
