Moldy biltong

I bought biltong from Meat world Gateway in Centurion and found mold on it when I got home, the sell-by date on the packet is 2 March 2021. This is not my first experience with old biltong from Meat world, the first time the meat had a funny smell and then we found worms on it a couple of days after the purchase. I would definitely not buy biltong from here again and advise anyone to check carefully before consumtion.
