I am not sure how much advice state Consumer Affairs offices actually give (as @gregr suggested) beyond the initial steps of communicating with the business one is complaining about. There after, they are nothing more than a mail distribution centre. You are right; they are a toothless tiger.
You might have a look at another topic from an experienced consumer advocate (@PhilT) which shows how difficult it can be get action against a business who is not willing to do the right thing.
