To cancel with with 30 days notice
1) Call 150 from a VM phone or by dialling 0345 454 1111 - select options 1,1,4,4, - thats the UK based retentions team - but calling at 08.00 is the best time to get through without being diverted offshore I would record the conversation too. "TOP TIP: If you're struggling to get through or are tired of waiting in the queue - you can try Virgin Media's cancellation and retentions department directly on…. 0800 952 2277 or 0800 052 2001 - no guarantee of getting through there either though

2. Cancel In writing to…
Include dates, name ,address and all account details. They say to also include your phone number so they can call you to confirm - probably to make you an offer to stay.
Do it by registered mail next day delivery guaranteed and with a receipt for signature on arrival.
Whatever you do DO NOT cancel your direct debit until the final bill has been settled or or it will cause all sorts of issues you dont want.
