Our health is not important to save Hyper stores

On Tuesday I went there to but kids lunch as one of the stores I trust, I bought 2 Melrose cheese spread,when I got home I noticed that the Expiry date was scratched out, i opened the first bottle it was rotten, decided to take it back and to talk to them, they denied everything, told me that maybe it was wiped out by the workers who work in that department, but refused to show me the rest of the stock, because I told them that people will get sick, they offered to bring back my money, I was so disappointed and wish that further steps be taken to ensure safety of our people
