If you have been sold a product that is faulty, the product or service must offer you a solution. This typically comes as a repair, refund or replacement. The business does have the right to assess the product or service before they offer a solution.
Businesses must meet a set of basic rights when they sell you products or services. These are called consumer guarantees. Whenever you purchase a product or service you are always covered by these rights.
If you have a problem with a product or service, always contact the business first to explain the problem and the outcome you want. Do this as soon as possible. Often, a single phone call or visit can fix the problem. You can also write a complaint letter to the business.
