Netflix unlinked from Virgin Media

I have Netflix included in my package, I activated it and it gave me the option to upgrade to Premium for £6 extra per month as it was Standard subscription included in the package, so I opted for this, and a couple a days ago I received an email from Netflix that my subscription is on hold as it is no longer linked to my Virgin Media account and I need to add a payment method.

I subsequently reached out to Virgin Media support who said they would resolve this, but I then received email to say changes have been made on my account and then received a new Netflix activation link, when i go through to activate it says its now Standard with Ads and if I want the Premium like I had before and have been paying extra for it will be an additional £13 per month.

Support say its logged under the complain reference of C-2908251534 but I'm not happy with the time its taking as I'm unable to use Netflix unless I add a payment method or link to my VM account, but I don't want to be charged double and the increased rate.

Is there anyone that can assist with resolving this so my account is corrected back to the £6 for premium?
