I didn't know that when you actually write a complaint about a product faulty packaging (in this case, the packet of cereal inside the box), they really took it seriously and responded within a week! I have blurred the product name for privacy purpose.
Not only that, they included a AU$10 voucher card & a shopping list as an apology. That's nice. The card can be used at Woolworths supermarket or Big W store (that's where we often buy diapers for Bee).
Lastly, it wasn't us who wrote the complaint nor bought the cereal. SIL lah, who else.
