Called Aerlingus today regarding multiple voucher requests submitted on 5th April. Unsurprisingly booking references for period around Easter 2020 weren't visible in the system so agent took all details and escalated with case references ( I didn't get any case references for my original online submissions).

Additionally refund requests which I submitted on 29/6 this time with case references appear to have been stuck in a queue so agent advised both refunds would be received within next 14 business days.

At last some progress!
