Success, thanks to Eeyore. Thank you Eeyore. I had flights booked in May and I originally requested a refund on 27th April via the email they sent me, (when the flights were cancelled), which included a link to apply for a full refund (outward journey to Reus). I did the same for a second booking two weeks later (return journey home from Barcelona). The only email I got afterwards were emails offering vouchers which I ignored. I waited patiently since.
Then Sunday night 20th Sep. after reading your post, I went to the link you kindly gave on your post and applied again for a full refund. Like you, I got the message back indicating that I was now in a queue for a cash refund in lieu of a voucher, which I had never requested.
But to my delight, I got an email on Monday for the Reus flight saying I would be refunded the full amount to my credit card and indeed it arrived in my bank yesterday Wed.
Even though I applied for the Barcelona flight within minutes of the other one, I only got the confirmation email today, Thurs., confirming they would refund me the full cost, so I do expect I'll get that in a few days.
I want to thank you very much Eeyore for your help, or I could be waiting forever.
I also want to flag for others that I got one confirmation email one day after applying, but it took 4 days to get the other Barcelona flight email, so don't despair if email takes a few days.
