PnP advert - laat chicken cooking are die staff

PnP had a special on for R100... This was a whole chicken, 6 rolls, and a 1.5l cooldrink. We went Friday and were told sold out at 4pm. We went again on Sunday at 12.30. we were told aold out... The had made 30 chickens die the morning already. We saw that there were more chickens cooking and upon inauiring what time they would be done...the answer was it's die the staff not the public. How can you advertise and not have enough... Why may staff have but nothing extra for the public. Dont advertise if you cant meet the quota!! Disgusted in their service
