Woolworth terrible customer service

At the canal store, the lamb was on special it clearly stated the new price at R109 for the pack not per kg however when I went to pay for the items it scanned at the full price. After speaking to the floor manager who had advised that those are generic, I then found a sticker on a different item which stated the discount per KG. Once the store manager Dean Langeman advised that I was 'allowed' to speak to him he requested to see the meat packs when it was brought to him the discount stickers had been removed.

Apart from wasting half my Sunday in the canal walk store I'm am more disappointed by the service I've received from the branch manager Dean Langeman who was so rude I'm still in shock at how rude he was stating that I should look properly and asking if I'm not able to see properly! Even though the sticker had been removed and I had taken pictures of them.
