Chickens did not arrive

I placed an order for Nandos Long street, delivery time was scheduled for 12:55. I called at 13:15 asking for an update and the call got cut while I was waiting for the order confirmation. Shortly after the meal was received (at 13:18). When checking the meal, I noticed that there was 2 missing items from the order (2 quarter chickens), and immediately tried to call through to Nandos Long Street (by pressing option 2), the phone just rang and no one answered after 6 attempts. I pressed option 1 and was told by the lady that someone will get back to me with an update. 30minutes later, no answer when I called again (by pressing option 2). Was looking forward to enjoying my meal as a whole but now I have to wait for the chickens to arrive. Unacceptable from such an awesome team and store that I support as often as I can. (maybe the chicken did not cross the road?)
