Dommo39 to Cable Forum
Sorry to note that you have been getting the run around.
Cable Forum , albeit independent of Virgin Media, have developed contacts who have proven good at getting these serious matters resolved. It you want us to intervene on your behalf, please PM me some details:
Account name and number, address, the phone number affected, a daytime contact phone number (mobile?), and ideally an email address. If you have any more information on the problem send that too.
