No attention to clients orders at all

Bought the all in one meal with 6 pieces, 2 sides and coleslaw. With and additional R30 paid for 4 rolls which i did not get. Customer service and paying attention to orders seems to be a problem at this KFC. Getting home dishing up for people and being inconvenienced like this is not on, now what? Should we be wasting our petrol going back to a store for what they should have made sure is included in our order.
