No stock, but advertise the special

I am very disturbed as i was at A1 chicken hyper on Saturday 29.08.2015 @ 6.30am to purchase the thighs as per the adverti*****t. I was then told they do not have stock. I left and returned at 8am again to check if the stock arrived. At that moment it did not and no one could tell me when they will get stock and if they will get stock. this is very disturbing as i had to drive up and down and no one even cared to take my number or showed some empathy. i always buy my chicken in bulk, but now i have to think twice. Hope some one will shed some light soon.
