If you would like to contact one of the UK based BT Care Team who moderate this forum, they should be able to help you.
They can be contacted using this link BT Care Team
They normally respond by phone or e-mail, within three working days, however you should get an immediate confirmation, with a tracking number.
So to update, I've now been told they can't put a line in and my home move order has been cancelled, but I have to pay to cancel the contract on the property I no longer live in. I appreciate BT is a business but it's not my fault they can't put a line in and this seems more than a little unfair. There must be a policy to cover this, I know other companies have. So now I have no phone, no internet, but I'm still expected to pay for my non existent service.
They are on dodgy ground there. Contact the Mods and they'll get this looked into for you (as per the link above).
