Promotion - Drive Thru service complaint

Good day, I was at your Bellville store a few minutes ago and I was very disappointed with the service and response I received from the person at the drive thru as well as the manager on duty(Auston). I wanting to buy the 12 piece Tuesday chicken special, the lady then advised that they were out of that, I asked her to explain as I was willing to drive to another KFC, her response was that she doesn't know and that her manager said they were "out". I asked to speak to the manager, who then said I should drive to the window where you pay. He then said the special was stopped but he doesn't know when but they will have the special in January again. Through all this he sounded very unsure as I asked him again, when it stopped and he said maybe this week or last week and there I was left hanging, that is it. I then spent close to 10 min in the drive thru line, as i obviously could not pass the cars in front or reverse as there were cars behind me as well. Please confirm if this special is still on or when the special ended. After an email was sent to KFC customer, the email was read but there is still no reply, I called another branch,the Parow Voortrekker branch and they confirmed that today is the last day of the special.
