Rotten food

I am so disappointed at Spar Cape Town Station, I bought pork on Thursday and to my surprise I cook it only to find out it is rotten it has a funny smell and the color is dark l, send email immediately to the email address on the slip but up until now the was no response what so ever from them and I could not return the meat because I don't work public holidays and weekends and I did not have a choice to eat the meat as I did not have any other option. I hope my daughter does not get sick from this
