How to complain
We do our best to make sure you always have a great experience with our network. But if for any reason you’re not happy, we want to hear from you so we can make it better.
You’ll find how to submit your complaint below. You can also raise a complaint on behalf of someone else, as long as we get confirmation of consent.
COMPLAINTS CODE OF PRACTICE Customer Complaints Code Making a complaint. 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. We've tried to make the complaints process as straightforward as possible and we aim to resolve all complaints within 14 days. There are a few different ways to register your complaint with us, and you can find them all on our How to Complain page. Our complaints handling process applies to our consumer customers and business customers of all sizes. If you wish to complain, our aim will be to resolve your complaint as quickly as possible. To help us do this, please provide the following: details of your concerns how you would like us to put things right your name and address your email address (we will only use this to contact you about your complaint) a phone number and the best time to contact you, as we may need to call you for further information any relevant agreement and/or reference number What happens next? We have two slightly different complaints procedures depending on whether your complaint is about the financing of your device, or for any other reason. Complaints in relation to the financing of your device If your complaint cannot be resolved within 3 business days of receiving it, then it will be referred to the Complaints Team. They will acknowledge receipt within 5 working days and explain how we plan to investigate it. They will also provide a copy of our complaints handling procedure for your reference. If your complaint isn’t resolved after a period of 4 weeks, we’ll contact you to explain why we haven’t been able to complete our investigation. If we haven’t been able to resolve your complaint within 8 weeks, we’ll give you an indication of why we’re unable to provide a final response and when we expect to be able to do so. You will also receive a copy of the Financial Ombudsman Service’s explanatory leaflet, setting out further details of the service they provide and how to refer your complaint to them. Once we have finalised our investigation we’ll respond to you with a final response. Our final response will either: accept your complaint and offer you some redress or remedial action if appropriate; offer redress or remedial action without accepting your complaint; or reject your complaint and explain our reasons for doing so. If you’re dissatisfied with the outcome of the complaint, you may refer it to the Financial Ombudsman Service within 6 months. Complaints in relation to anything else While we aim to solve problems straight away, more complex matters may take a little longer. If we need to look into your concerns, we’ll send you an acknowledgement of your complaint via SMS and then commence our investigation. Once we’ve reviewed your complaint, we’ll tell you the outcome of our investigation. We aim to provide you with our final response to your complaint within 8 weeks of us having received it. If we need more information to help with our investigation, we’ll contact you first by phone. Alternative Dispute Resolution If you’re not happy after we’ve given you our final response to your complaint or 8 weeks have passed since you told us of your concerns, you may wish to ask one of our alternative dispute resolution (“ADR”) providers to investigate your complaint by contacting an Ombudsman. We’ll send you an ADR letter by email or post to let you know when you can take your complaint to the Ombudsman. The Ombudsman you can contact depends on the nature of your complaint. If your complaint is in relation to the financing of your device, then you can ask the Financial Ombudsman Service to independently review your complaint. For everything else, you can ask Communications Ombudsman to help. Both the Financial Ombudsman Service and Communications Ombudsman are independent organisations dedicated to sorting out disputes between businesses and their customers. Their services are free of charge and Three will be bound by their decision if a case is opened. You can find out more about the Financial Ombudsman Service or contact them directly by the following methods: Post: The Financial Ombudsman Service, Exchange Tower, London E14 9SR Phone: 0800 0 234 567 or 0300 123 9 123 (mobile) Email: complaint.info@financial-ombudsman.org.uk Online: www.financial-ombudsman.org.uk Alternatively, you can find out more about the Communications Ombudsman, or contact them directly, by the following methods: Post: Communications Ombudsman, PO Box 730, Warrington, WA4 6WU Phone: 0330 440 1614 (Monday to Friday, 8am to 8pm, and Saturday, 9am to 1pm) Email: enquiry@commsombudsman.org Online: Ombudsman's website Just so you know, Communications Ombudsman will not be able to deal with your complaint if it falls outside its remit. If that’s the case, they’ll let you know and explain why not.
