Disgusted

This evening my son ordered Burger King via Uber Eats. Order #D6B38 , driver names Adimaya. The food came to R106.89 my son advised its cash order. Driver arrives at 8.42pm and he tells my son it's his 1st run and he has no change .. drives off with R93.11 its daylight *******.. when I contacted him he advised his too far away now and my son said it's ok. I told him I wanted the change back and now his not taking my calls
