KFC inconsistency and confusing customers - Observatory Store

KFC Observatory Store ( Cape Town) Went to buy KFC at the Obs store and I asked for wings to be excluded, this is always my request when I visit this store or any KFC store and this has never been a problem until today. The lady at the counter refused and said this isn’t allowed my order will contain wings. I cancelled my order and told her that I will lodge this with Hellopeter but she couldn’t care.
