Consumer Guides


Information on goods or services must always be adequate and timely. We have prepared this Consumer Guides section to provide you with in-depth information on providers’ obligations, as well as the mechanisms in place to help protect your rights and how to use them whenever you have a problem when making a purchase.

Here you’ll find guides and fact sheets with information on common scenarios in which you may find yourself when purchasing a good or service, whether you are shopping at a business establishment or using public utilities (water and sewerage, electricity and natural gas, public transportation infrastructure, and telecommunications).

We’ll help you learn the procedures you need to follow, step by step, to file a complaint or claim with a provider anywhere in the country.
