Beautiful restaurant BUT appalling service

Went to KFC protea glen mall, bought a share meal worth R154, Firstly I dont get why I should stand in line to make the purchase and still wait in line to collect my food. What happened to them calling out order numbers? As if that is not disappointment enough, I get home and the box has 4 pieces instead of 5 and its very small pieces as though they are from chicks. This is an appalling service from such a big restaurant. I stay 30 min from the mall there is no way I am driving back to query this... The renovations are pretty useless if the service is so poor and careless.
