Kfc head office doesn't reply

On Sunday 20 Dec 2015 my family went to KFC V&A Waterfront for dessert. We stood in a long queue and when we got to the counter we were told there's no oreo biscuits for kream *****. My problem is that other branches put up signs when there's no stock. Why can't they put up signs at the waterfront. We wasted our time standing in the long lines. Also while standing in line, this tourist was talking to her husband and she said they were standing in line to order desserts and when the got to the counter, they were told they're in the wrong line. And the staff wouldn't assist them. So they had to queue again in the dessert queue. Is this image KFC wants to portray to the tourists? Really pathetic. I've submitted my complaint 21 Dec on KFC's fb page and twitter and I was told someone contact me soon. I'm still waiting. How long does it take? U can't possibly tell me that KFC head office that busy. That's why I'm posting my complaint on Hello Peter to get quicker results. Or maybe it seems my complaint isn't important. This all could've been avoided if someone just contacted me when they told me they would.
