Flights cancelled - how to get the WDW tickets refunded?

Hi, as expected Virgin have now cancelled our 17 Oct flights from LHR-MCO - it will be refunded, all good.
BUT I bought our disney tix direct taking advantage of the 14 days for the price of 7 UK-exclusive deal. the T&Cs say non-refundable and non-transferable and they expire at the end of the year.
Any advice on how to play this? Get credit toward future tickets? Try to push back because they shouldn’t be selling tix to UK residents if we aren’t allowed into the US (granted, this will work better if we get to the end of the year and still not allowed in) OR try another route (credit card charge back or holiday insurance)?

Any and all tips are welcome, Im talking about almost £2000 here so it’s worth pursuing.

I think there’s a possibility they will refund them given that we can’t enter the country. The value can always be used towards a ticket at a later date but if you’re staying onsite most of the time you’ll want to book a package to get whatever offer is available.
