You'd be entitled to get your points back, although of course what practical value they have under Virgin 2.0 remains to be seen.

In theory you should also be entitled to a refund of the 'fees & surcharges' component, but that'd likely land in your lap as one of these 'conditional credit' vouchers - despite the Govt agreeing to waive fees for airlines as the first part of its relief package some months back - so I'd suggest looking into a chargeback via your credit card based on non-delivery of service.
