Had a flight to Dublin cancelled and Italy rescheduled and requested a refund .. was originally told this would take a bit of extra time and would have to wait.
Due to the ongoing COVID-19 restrictions I waited a few months then contacted Ryanair 10 days ago.
Got both refunds back within timescale they promised.
All I can say either be patient and wait or contact them on the on line chat.
Only used them once before and was happy with flight and price..probably use them in future but will wait when all back to some kind of normal.
