Do you still have a normal DialTone if you plug a phone in the jackpoint with your xDSL connection? if so your phone line is still active - Talk to your provider
Do you have a tone that sort of sounds like you would hear when you ring someone ? If so you have what is called NU-Tone and the line is still live but deactivated (this is normal) - With a line with NU-Tone there is no 'phone number' attached but you can still dial 111 and nothing else (pls dont try it to see if it works unless its an emergency)
When you dial your home number does the phone attached to your Genius ring?
If so all good. You can pm me your account number and I can get our provisioning team to double check the pots is deactivated, depending on your previous provider they may not have actioned the relinquishment on the pots service yet.
