Thought I'd give quick update incase anyone else has similar issues or looking to move from Vodafone.
Rang Virgin to close my account as they confirmed I am being connected via EE! apparently if you order online this happens and are not guaranteed to connect via Vodaphone masts, but if you place the order over the phone it will be via Vodafone masts, regardless if you are want 4G or 5G! Not as simple as them changing it over for me now, they would have to close my current account down and then call them to set new one up!! Uhhhh
Seems bit bizarre to me, so moving over to Voxi (thanks for the suggestion) with my Pac once the phone is returned everything is cancelled.
Much appreciated again to all the helpful peeps.
