As far as I can tell they should not have sent me another bill.

Morally, I would agree if I have understood your timings correctly and you have no usage charges. Your last day of usage would have been 9/3/22 and disconnected on 10/3/22.
If I have understood VM's billing processes correctly (which I am still grappling with myself), then they will look at the account when it ends and create the final bill (which for some might include usage charges in arrears). You get billed in the next period which covers any charges in arrears, during which time you return any equipment and VM still has your credit to cover any of the above possible charges or non-return of equipment. In theory, they refund you the balance once the above has been paid off and any equipment has been returned.
I am in a similar situation crossing into a second billing period yet not using the service at all, having no usage charges and using an ancient hub 2ac which I do not expect they will want back yet will still have to pay for a further month then wait, at VM's leisure, to generate a cheque.
If the above isn't correct, you'd have to put together your case for VM to review. In the meantime I think all you can do is track what is going on and make sure the steps along the way are being completed correctly. Very difficult with a company that has made itself non-contactable and whose administrative processes are so unreliable and opaque.
