I'm also in the same boat.
The activate button is there and only ever leads to the plan selection page inviting me to pay for Netflix.
First offered Netflix included package on 20th April. No activation emails were ever forthcoming.
Chased up on 13th May to be told that it wasn't included on my package despite it being clearly offered on my previous call. But fear not, they could amend my contract to make sure it was included....... Still no activation emails.
Chased again on 13th June via WhatsApp and told
Apologies for the inconvenience caused to you. There might be some technical issue due to which you are not able to access Netflix. I'll get the IT ticket raised for you and within 48 hours it will be resolved.
Of course we are long past 48 hours by now, and still no contact from anyone. No activation emails. Activate button still invites me to pay for Netflix.
The length of time this has gone on for and the lack of communication and customer service is, amazingly, a new low for Virgin Media.
Netflix won't be happy either as I'd previously had a subscription with them which I stopped when I was told I'd get in inclusive with my package. I imagine many others will have done similar.
