An opportunity to cheat a client

My experience with Chicken Licken Boulders is a disgrace. The first time they deliver my food they don't bring my change and leave without giving me change of just over R20 he tells me he will come back with the change yeah right I am still waiting. Then today I order again and they bring only half the order with no hot sauce and then wants me to pay the full amount for the food and then will bring the rest later, NOT FALLING FOR THAT ONE AGAIN!! Then I pay you the full amount and I never see the rest of my order again. Very very very very very poor service!
