Pick'n Pay Rotten Meat **** 'Special Offer'

I recently purchased meat from Pick 'n Pay Westville and noted a terrible smell once opened. I noticed that the sell by date was the 27th of February. Upon closer inspection of the label sticker I noticed that there was an older sticker behind the new sticker and it had been *******ly hidden and covered by the new sell by date. The old hidden sell by sticker stated that the original sell by date of 22/02/2015! When I returned to Pick'n Pay I alerted the management of this (Alistair) and they did not seem interested. They casually removed a trolley full of *******ly labelled meat. If Pick'n Pay has not sold their expired meat they simply spice it up, extend the expiry date on the label and put it on as a special offer! How many people have to get food poisoning before something is done about this? I have emailed head office and no one has got back to me.
