I have been speaking to Virgin Media Customer Service and to VM complaints this morning, using BT POTS at my end. I understand that there is a local (I am in KT3, New Malden) telephone system fault which at present is occupying all their available engineers, so they cannot at present consider the telephone part of the complaint - that is reasonable.
Usenet uk.telecom and uk.telecom.moderate, on Google Group, appear to be effectively inoperable.
Does anyone here know anything about the current status of VM phones in KT3??.
