Complain of receiving old sausage

I’m am a very upset and irate customer. Yesterday I forgot to take out what I wanted to cook from the fridge. I then decided on my way home to go and buy something at pick n pay in doringkloof centurion. I bought a packet of sausage took it home to cook it. I then dishes up for everyone I was the one who ate 1 st but thought it was just me who is tasting sour and off sausage I continued eating when everyone started experiencing the same thing I knew this sausage was old. I then started vomiting and decided to complain in their website as well. We threw the sausage out because it was sour and old. Went to bed and the whole night I experienced stomach pains and had less sleep. I am so disappointed at pick and pay as they have put my family health and mine at risk of being sick. This is really upsetting and disappointing I’m not a happy customer at all. I don’t know why they sell old meet to people.
