I've tried all sorts of avenues for a refund and been unsuccessful. I've quoted timings, previous policies, CGA, change of CoC recently, they cancelled for ops reasons not government restrictions. Even the expiry of the credit is dodgy, they say it was issued on the 12th of March despite the flights not being 'cancelled' until 27th March. On the 12th of March there was no hard line government restriction on travel. TBH I've had enough trying to deal with it, I've better things to do with my time.

if anyone manages to get a refund let us know

They used 'suspensions' which were clearly for operational reasons, that then brought them time to wait until the government restricted travel and then they rolled out 'cancellations' for the already suspended flights citing for reasons 'out of their control' which = no refund.
