Preparing a dessert incorrectly & missing item

On a previous visit to KFC at OR Tambo International airport, they had run out of stock on buns of a certain size so I could not order a Double Crunch Burger but would have to settle for a normal Crunch Burger. Accepting this as a once-off thing since I'd never experienced anything of the sort at any other fast food franchise, I ordered a Crunch Burger instead.<br> <br> However, on this visit to KFC I ordered a Choc Crumble Kream Ball for the fist time and received vanilla ice-cream with chocolate sauce and no crumble . The lid had been hastily placed on, so chocolate sauce leaked out the side. I queried the lack of crumble with the lady who served it and she was certain she'd done it right. Nevertheless, she called her manager who confirmed that she was wrong and had missed out the crumble. She did not react to correct this but instead her manager scooped crumble into a plastic container and handed it to us, expecting us to figure out how to place it under the ice-cream. I requested a new one be assembled instead and he obliged. When we reached our home 35 minutes away, we realised the mini loaf we'd paid for was missing from the bag. Such poor service is unacceptable!
