How to complain.
At Three we always want to make sure you have a great experience and we hope that you'll never have reason to complain about our services. However, if you think we haven't done a good job we'd like to hear from you. We’re also happy for someone else to raise a complaint on your behalf, as long as we have confirmation that they’re acting with your consent.
We've tried to make the complaints process as straightforward as possible and we aim to resolve all complaints within 30 days, so get in touch using one of the methods below to register your complaint.
Contact us.
Our dedicated Customers Relations Team are trained to handle your complaint and you can contact us online by using Live Chat.
Following governmental advice related to Coronavirus, our Contact Centre staff are struggling to get to work, and therefore wait times may be extremely long. We’re really sorry about this, but we are working hard to be able to provide support for our customers, and thank you for your patience during these difficult times.
Live Chat is open from 8am to 8pm Monday to Friday, and 9am to 6pm Saturday and Sunday.
Call us.

Contact the Ombudsman.
If your complaint still isn't resolved after contacting us using the above methods, you can ask the Ombudsman to look at your case for free.
If we are unable to reach agreement within 8 weeks we will provide details of how to contact the Ombudsman.
The Ombudsman is an independent organisation dedicated to sorting out disputes between customers and providers, and Three will be bound by its decision. You can find out more about how to complain to us by reading our Customer Complaints Code.

Online purchases.
If your complaint is about a purchase you made online and we’ve been unable to resolve your concerns through our complaints process, you can submit your complaint through the European Commission’s online dispute resolution platform, instead of contacting the Ombudsman directly. You can find the platform and more information on how it works here: http://ec.europa.eu/consumers/odr
The platform simply facilitates the investigation and resolution of your complaint through the Ombudsman so, if you’re unhappy, you may find it easier to contact the Ombudsman directly. Remember, you can only use the platform if your complaint comes from an online transaction. If you made your purchase over the phone or in store, you need to contact the Ombudsman using the contact details above.
