Mango disappoints

It's been a bad experience this far with no communication. I booked airline tickets for my family for April 2020 due to virus it was cancelled and ever since that announcement I have been phoning Mango airlines to be told I have to email they cant help me over the phone then I send email after email to try and request t a refund and to date no reply. Absolutely shocking and disappointing. This is poor service, a refund should be given and some form of communication Anyone else battling too?
