What do you actually want to do - reduce your bill or leave for a cheaper provider?
Leaving is easy. You have to give 30 days notice.
1. Call 150 from a VM phone or by dialling 0345 454 1111 (standard rate number - in your bundled minutes) then follow options 1,1,4,4, from they are still picking up - calling at 08.00 is the best time to get through quickly
2. Or in writing to...
Virgin Media Sales Operation Support,
Diamond Plaza,
Daleside Road, Nottingham,
Nottinghamshire, NG2 3GG.
Include date, name, address and all account details. Do it by registered mail with a receipt for signature on arrival.
Your bill has doubled because you have come to the end of your discount deal and the price has reverted to the same standard price as what everybody else pays, which you agreed to when you started the contract.
If you are not happy with that then you call the cancellation number (above) and negotiate with them. They will probably give you a more attractive deal in lieu of you agreeing a new 18 month contract. But that's not guaranteed of course
