How do I make a complaint about my broadband?

The answer

Start with the provider's customer care, using the contact details on your bill or official website, and ask for a complaint reference. If it is not resolved in the stated time, follow the provider's published grievance process to the next level, quoting your reference, and then put the matter in writing. Keep dates, names and copies of every step. The National Consumer Helpline lists a toll-free number, an online portal, an app and WhatsApp for consumer grievances. See the guide on complaint routes.
