Rotten Joes Frozen Burgers sold at Khayelitsha SuperSpar

I am super dissapointed in Spar Khayelitsha Mall, on the 24th Jan I bought my groceries and with that I bought Joes Burgers for my daughter’s lunchbox. I only started using the burgers last week Sunday preps for Monday, burgers had a foul smell, smelling sour I only took out two and I put them back in the freezer, only to use them again today, the burgers are frozen but you can smell the sourness and I only took note of the colour, the burgers are greening meaning they are rotten, I have picture. I am writing with the hope that they will call me back so I can show them the picture as Ii am not able to visit the store during week because I am working.
