I'm in the same situation too! I'm now getting bills addressed to my dead father at my home address! My dad never lived there while he was alive! I spoke to someone in the Bereavement Team yesterday evening, as previously they had beet better to deal with than the general enquiry people, but the guy firstly wouldn't accept that the bill had come from Virgin Media at all, even though I was holding it in my hand! He insisted the post office had forwarded it on! He had not one care for the fact that I've lost a loved one and am now having to unravel the mess they have created!
When I eventually convinced him it had come from Virgin Media, he looked through the file, and it appears that my address has been put on the file for forwarding bills to. I've never agreed to this, and was actually told, like others, that the final bill would be waived and there was no need to pay it. Now I'm concerned that my address will be linked to an unpaid bill and my credit rating affected, even though it's not my bill!
This is all on top of the nightmare experience of getting a new account set up in my mother's name. This is still ongoing, since last November! She is now eventually set up with her own account, BUT we're still waiting for the phone number to be changed back to the one that her and my dad have had for the last 25 years! I was originally told it would take between 48 -72 hours. That was a week ago and it's still not gone over. I contacted Virgin Media via the chat yesterday and they told me that the number has now been allocated to my mum, but it can take 2 weeks to activate!
Honestly, I have never dealt with such a terrible company!
