As others have suggested, as long as you are refering to the "master" socket in your flat, you need to get BT out to check the phone and make it works - BT have descended into a terrible farce - off shoring their help centre HAS made things worse.
4 years ago, we moved house , just down the road. The Friday before we moved the local BT man attended the property, checked out the new master and transferred our number to the new house - to his credit he hung around long enough for me to hook up the HH5 and check my laptop was connecting to the internet.
One the Monday another contractor came along and connected our new house to the number of the person who bought our old house - which we didn't realise for about 3 days until a somebody rang to speak to the new buyer
Needless to say the off shore BT call centre didn't believe me - so when asked them to confirm the number I had called them on - they said "but that isn't your number" - I then got transferred to a UK help centre and a very nice man arrived the following morning - sorted the problem in a matter of a few minutes
We were without our landline for 1 week
