Pick n Pay - False advertising

False advertising.
So I went to PnP hyper Boksburg for one hour only sale, when I got to store at 7 15/7 20 there was no stock of any of items advertise and I was running around store asking staff for help and no one help , finally found a manager and I was told I was to late , friend of mine was one of first in the store and she also confirm there was no stock when she was there either how can advertise good that aren't even there ? Person drive far and goes early to store to have this disappointment.and still have no one who helpful or know where anything is
