Utterly disgusted!!!!

KFC has been offering a less 50/50 deals the whole of this past week. On Saturday morning going on their website, the deals were still there. Later the morning towards lunch time, ready to place an order I noticed that the deals were blocked out. I called the Customer Service and I was told that the deal had expired the 15th. Then I asked if that was the case, why was it still advertised the whole week and demanded to speak to the Team leader and was promised she would call me back. It is now 19.15 Sunday evening, and nobody has bothered to return my call. It just shows that they had noticed that so many ppl had ordered online so they blocked the deals, so they can make an extra buck. That's trick advertising. I'm not the only person that noticed that. This leaves a bitter taste in my mouth.
