Expired goods

I was in the canal walk store last week Sunday and spent just over R1500on a few essentials I needed for my home. Later that week I make myself a Vienna sandwich for work and not too long after that I fell ill. Today is day that that I have been ill puking my guts outs out and so weak. I tried to figure out what I ate to cause this and seeing that the Vienna’s was the last thing I could eat I checked the packaging and it was past the expiry date. The ****ins my wife made with the ready mix was also nearly a month past the expiry date. I called the store and not sure the lady I spoke too but she requested I return the packaging and till slip. I did so much shopping that day and not sure what my wife did with the slip and the packaging was wrapped and disposed of as I have 2 boys both under the age of 3. I feel this is unexceptable to sell expired goods. Yes it’s a human error but then treat your customers in a better and not just blaming your customer. I look forward in hearing from a senior manager in store and not just a till packer that can’t take responsibility for their actions.
