Coles Supermarkets Australia

Sir,
I bought two "Indian Inspired Butter Chicken" product code:9 300601 387502 with a use-by date of 31/01/20.
My wife and I were very disappointed as when we opened them after heating we found it hard to find any chicken in the source at all, it was if someone forgot to add the chicken.
This it's sad to say is the way many companies are trying to improve their margins by making the customer pay more for less by stealth. which I believe is a folly.
I hope that Coles isn't one of this type of company as the opposition is only just down the road.
