The whole VM/Netflix fiasco seems to have been going on for quite long enough now. VM have offered something, you've accepted the offer, VM have failed to deliver. That's a breach of contract. Given the enduring issues, I'd suggest you (and indeed anybody else still affected) contact Citizens Advice.
Alternatively you need to complain to VM using the web form in My Virgin Media, state that they have failed to honour the terms of the contract, attempts to rectify this failing have been ineffectual and you hold them in breach of the contract under the terms of the Consumer Rights Act 2015, section 52 . State that you are now making "time of the essence", offering them ten days to honour their commitments and provide you with the full service, and additionally to pay compensation for the weeks/months of delays, and as a separate item to pay compensation for the poor customer service. I'd suggest £15 a month for failure to provide the Netflix service, and £60 for the poor customer service. Maybe that will get the required outcome, but realistically VM's complaint handling has been so poor you should expect to be fobbed off. If that's the case (or they agree to some but not all of your requirements), then you reject the resolution email and ask for a deadlock letter. With the deadlock letter you involve the industry complaints adjudicator (and a further compensation request of say £50 for the poor complaint handling).
If the forum staff can intervene to sort this it will be easier for you, but use the complaint route if VM don't offer a settlement ("goodwill credit") that's of an appropriate value.
