False advertising

Went to Kfc for the 6piece chicken for R65 as today is today. I was told by Vinesh the manager of Kfc Austerville in durban that they do not serve this promo on month end week. I addressed that this is not verbalized to us as. Loyal customers to Kfc nothing in writing to us as customers which is false advertising. I then went on to Phone Jenna their regional manager and asked what is done for a customer like me who has come from home for this special she then said nothing can be done. I'm absolutely disgusted at the behaviour for a regional manager as the customer did not come first which is disappointing. Kfc let's minimize false advertising to loyal customers
