Misleading and False advertising

I walked into KFC ladysmith the one at the Pik n Pay centre on the 6th of September attempting to purchase the R99 Super Sunday deal but the lady at the counter told me that it was only available in August and is no more.

Yet I came home the very same day and was watching Family Feud South Africa on E-TV at 18:00 and I see KFC advertising on TV for the above deal and the advert for the deal played a number of times. I sent a e-mail to KFC complaints but nobody has contacted me. Why must KFC inconvenience the consumer and mislead us with false advertising.
