Very poor service from debonairs celtis ridge

On the 24th August 2018, I placed an order via the app at 19:29... waited for my food to be delivered and the delivery guy showed up at 20:55. So I waited for about an hour and a half... and then to make things worse the delivery guy had the wrong order. Tried calling the shop but that was just a waste of my time and airtime because the call was never answered. I'm really disappointed in the service from debonairs celtis ridge.

All the delivery guy did was laugh when I told him it's the wrong order, and he just said must I bring you the correct order??? So you expect me to wait for another hour for a mess up from your side?
