Dihorrea from Prepacked food-Spar Melville

I bought lunch at Melville Spar yesterday and tell you i did not sleep the whole night. The food that was packed gave me such bad Dihorrea will never buy their pre-packed food again The food looks like they were left overs from the previous day and they pack and sell to people. I'm at work and im still feeling very sick,im truly disappointed as i trusted Spar
