Items on special but no stock in store

I got an Incredible Connection pamphlet and the Xbox One was on special. The following day which was the 17th December 2015 I went to Cresta to purchase the item but the was not stock I then visited an addition 5 stores and no-one hade stock. I called the head office trying to talk to a customer service manager but clearly customer service is not important to this company because I was just dismissed with no-one returning my call. I then called the call centre and they were of no help I was just informed that a complaint would be logged and I will be called. How can you put anything on special if you do not have stock because the next day they were out of stock this is ridiculous. Clearly this company does not care about it's customers.
