Products and services receiving a disproportionate number of complaints are to be referred to the appropriate authority within the business. It could well be that appropriate modifications may be required that would not only cut complaints, but also reduce costs.

Complaints may also precipitate a review of a system or service.

There may be occasions that a customer complaint not settled by a business may go to an ombudsman, eg Telecommunications, banking or private health insurance. To avoid further difficulties you will need to make yourself fully aware of any Regulations that you must comply with.
