Rotten food/meat

I bought some food at the sasol filling station yesterday, rice and stew to be exact. The food looked good until finished eating..I had a runny stomach since yesterday after eating the food and today I went back to get a drink and I asked the ladies at the food counter as to when the stew was cooked and I couldn't get a definite answer..the meat tasted like it was cooked 3 days ago..it's wrong to sell rotten food to customers as I am writing this now I am still having a running stomach.. food like that should be thrown away not recycled..health inspectors should do a visit because it's a health hazard for people..
