Expired goods

Hi,<br> <br> I bought from spar in hilbrow ( Twist and smith street) . The goods were expired. I went to the store to complain and they told me they require a slip. It was a spar brand. I then laid a complain with their head office on the 14th of may. I was promised a spar voucher and advised not to go back to the store.I then sent another e-mail asking where my voucher is then I was told its on its way. Today the 08/06/2014 after inquiring again I was told the card was only posted today. What kind of service is this? Ms. Luyanda Dlamini is responsible. This is not on,they cant have expired goods on their shelves.
