Home phone line dead

My home phone line has been dead for a few weeks now. No tone, no nothing - definitely no calls.

Five weeks ago I received Virgin email advising me of plans to switch lines in my area over to fibre, but have not received any communication telling me that is actually happening, nor any adapters so I can plug phone line into router. 

When I check phone service on My Virgin Media it insists everything is fine with the line and equipment in my home.

Obviously cannot call 150 to ask for more help and I've given up waiting for a human on the 0345 line.

Is there a way of checking whether lines in my area have switched to fibre and it's just that no information was sent to me? What else might the issue be? 

Thanks
