Becareful of Mr Delivery guys they scratch in your food

Ordering food and when received you find food missing. I ordered from KfC 2 street wise 2s. When I received my food one piece of chicken was missing and the Tamatoe sauce sachet in the box. Both husband and mine supper destroyed. I suspect the Mr Delivery scratched in our food. When I complained to Mr Delivery they refunded me with a R30 coupon. Not even the meal cost R30.
