What to do if you receive calls from companies pretending to be HHH
If you've been contacted by another organisation claiming to be h (company name) and they attempt to upgrade your phone, sell you insurance or take your bank details, please let us know. Some of these companies may sign you up to something you weren't expecting.

We've already taken legal action against companies who have led customers to believe they are calling from hhh(company name). Two of these companies were trying to sell mobile phone insurance.
Our advice is:
 

    We only ever discuss our own range of phone insurance, hh Insure, which you can find at hhh.co.uk/insurance. Our phone insurance Administrator is "Ace".
    If you receive a call from a company claiming to be working with hhh, do not give out personal information. Try to note down as much information from the conversation as you can and let us know by calling our customer services number on your bill. Your call may help us identify who they are so we can take action against them.
    You may receive a 'welcome call' from us soon after connecting which may include details of our own range of phone insurance products. You can tell it's us because the number shown on your phone will be 0845 863 0287. If you call us back on this number there is a recorded message to give you confidence it is hhh.
    If you feel you've already been mislead into taking insurance you should take this up with the insurance company and ask for their cancellation and complaints policy. You may also want to contact Ofcom or the Financial Services Authority to report the practice of mis-selling and breach of distance selling regulations.
You might also want to register with the Telephone Preference Service, as they can help prevent you receiving further nuisance calls. You can call them on 08450 700 707. Or you can visit them online.
