expiry goods

My and I purchased a ****in mix (brand ****ins ) 3 days ago. Yesterday when she wanted to use it she noticed the date. She then went to the store to return it but didnt have a slip. The lady said that they couldnt help her as she had no slip. Now I am sure u can understand how my wife was fuming as she is pregnant and dnt have time for drama. My question to you is why have expiry product's on your shelves in the 1st place. What if she had to consume it and something happened to her and my baby. I am not someone to complain but I feel the service u gave was bad and will be looking forward to your response regarding this. Please email me on [Email Removed] or you can call me after 5pm.
