Which action should be the first step in dealing with a problem concerning a product or service you purchased?

The first thing you need to do when you encounter a product or service you purchased is to make a phone call or go back to the store where you bought the product or service. This way immediate attention will be given to your concern. 

If there is a delay in the resolution of your product or service defect, it is better to write a letter of complaint after making a phone call. This is to ensure that your complaint is properly documented.
