Christmas cheer is over.

Crossed lines.
Have you tried dialling 17070 from your home phone and checking that your correct number is in service on that line.

Finally the issue is now resolved after making a complaint, They called me and said that they have received the engineer report saying that he was unable to activate the line and they have now cancelled the first month bill + charges.
All I have to do now is wait for mailing bag to send them back their router.

There was no dial tone to make a call, their phone line was completely dead so I couldn't call any number.
Anyway the issue is now resolved after they have received the engineer report that the line wasn't activated, I have now renewed my contract with virgin.

Shame we will never find out who made those calls that appeared on the bill for the telephone line that never got installed.

Yep, I wish I asked them about it
