Failure to connect your new property whilst insisting you're still in contract amounts to a loss of service. Under the relevant Ofcom rules, that's about £200 VM owe you already, and still increasing.
So what do you want now? If you want to terminate the contract without paying an early termination charge (and being paid the £200 that they already owe you), then you need to complain to VM using the web form in My Virgin Media, state that they have failed to connect you promptly 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 under CRA 2015 and to pay compensation in line with item 3 below, alternatively to:
1) Release you from contract without penalty as provided for by CRA 2015 section 54 (7f)
2) Refund of all payments made since you last had a working VM connection and without further charges as provided for by CRA 2015 section 54 (7b).
3) Payment of £8.40 per day as per the Ofcom rules for compensation in regard of loss of service, to be paid between the last date you had a working connection, and the date that the company confirm to you that they will resolve the matter on these terms. The value of this is per Ofcom, the basis of your claim would be CRA 2015 section 54 (7a),
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 those three 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 for the poor complaint handling).
