No stock and no response - pathetic!!

We went to Pick n Pay Hypermarket at Centurion Lifestyle last weekend just to find that most of the items that was advertised on special was not in stock. I then send Pick n Pay an email with NO response. Today we went back and once again majority of the items advertised was not in stock. This is utterly ridiculous!! Why then advertise or have stuff on special, you wasting our time having to go out to the shops for nothing and risk being around people. This is truly a slap in the face and this is not the first time that this has happened. We feel stupid for even keep on shopping at Pick n Pay if this is the same thing over and over. Maybe you don't need the money and that's why you don't care to stock the items advertised or call people back.
