Rotten meat

Spar Mall@55. I love this Spar, we buy about 90% of our groceries there. I also always buy my Biltong there. I buy biltong on the weekend which is my snack during the day for the upcoming week, and the next weekend I buy again. For the last 2 weeks now, the biltong I get at Spar Mall@55, by the next day it smells terrible, and its rotten. The next day!!! I mean this is biltong, what are you guys doing wrong that you are rotting the biltong??? Seriously. This is starting to make me doubt the way you guys work with meat. Ag no man Spar, I am very disappointed!
