Dissatisfied

I bought food from the Nandos app yesterday, when my order came it was incomplete. The juice that comes with the Nandinos meal wasn't there, when I tried to call the driver about it he ignored my calls. Also, he was short of change and instead of giving me R50 change he gave me R40, that was on top of the tip I had already given me. My order number was 5697 from the Pretoria North nandos.
