Tips

When you find a problem with the item you buy, contact the retailer straight away and tell it you want to return the item. Don't use the item if you decide to return it, or the retailer may reject your request for exchange or refund. If the item has to be installed or fitted before use, don't allow this to happen if you know there is a problem with it.
