pretty easy if you send the cancellation letter to the correct company
I did - to Virgin Media's registered address in the UK. Forty days later, I have still received no response. How long does it take to pass a letter to the appropriate department within the same company? Had I sent it to, say, Barclays Bank or if Virgin Media's registered address was in the Cayman Islands, I could understand the lack of a response. As it is, it is just another example of Virgin Mafia's utterly woeful customer service.
