Flight for April to be reimbursed

I bought a flight ticket for my mother to travel early in April in time for Easter, however due to the current situation with COVID-19, it is discouraged to travel even on domestic flights. I have phoned the call centre and nobody is answering and I have also e-mailed, but the e-mail bounced back with a full inbox. I saw on your website that we may change our flight date without any additional fee, however I would prefer a reimbur*****t as we do not know when it would be safe again to travel. Please can you get back to me so I know what the next steps are and what you suggest in line with the COVID-19 guidelines?
