There is the possibility that someone at the exchange has switched of your landline .
This happened to me earlier this year I had Broadband but no phone for 3 weeks.
turned out to be a mistake by an engineer When I moved from Sky to BT and for some reason the BB was switched on but the landline for some reason was not.It took three weeks to sort out .I also ended up with a new phone number .
