I'm having exactly the same problem.
I have my Ultra Netflix account @£11.99 a month taken straight off my Debit Card. No problems with this and I want that Netflix account.
We also somehow have a Netflix account @£8.99 a month that we are being billed for by Virgin. Now, it's entirely possible that someone got mixed up and subscribed twice to Netflix but the second £8.99 account is not attached in any way to my Netflix account and the money is took through our Virgin Media bill.We sent all our Virgin TV boxes back a couple of months ago and changed our contract to Broadband ONLY.....still get £8.99 took out by VIRGIN through a VIRGIN BILL for a Netflix service we can't possibly watch.
Netflix cannot cancel it as they cannot identify it - it's not linked to my Netflix account.
Following the Virgin Help links to somehow rectify this doesn't work. The Netflix recovery link just goes through to the normal MyVirgin page with no mention whatsoever of Netflix.
