@Paynies importantly, have you cancelled your existing service with Sky yet? If you have then that automatically puts a stop to any chance of the number porting over - neither VM's nor Sky's fault here, these are the regulations.
What usually, or at least should happen, is that you sign up with VM and request that they port the number across from your existing provider (Sky in this case), VM install your services and give you a temporary phone number - what is vital is that the old number has to be live and working and there MUST NOT be any sort of cancellation request against it. So if you have called Sky and told them to cancel your contract as of .... then that will immediately cause the number port to fail and you will lose that number.
If you have cancelled, then your only option is to get back to Sky and cancel the cancellation (if possible) and ask to be put on a rolling monthly contract. Then VM put in the number port, once it goes through, that number replaces your temporary VM one, it automatically cancels the Sky telephone contract (you can't have a phone line with no number attached) and by its nature, also cancels any Sky broadband.
Not too sure about the Netflix issue though, presumably you have a Netflix account even if it was set up via Sky, if you have those details are they not working now? Were you paying Netflix separately or was it being billed as part of your Sky package? If the latter, then I'm not even sure if it is even possible to transfer that to VM and it may be that Sky have simply cancelled it
