Airlink service is non-existing!

I have been trying to get a refund out of Airlink since COVID Lock down started. I booked a flight for 27 March 2020 but because of COVID could not fly. It took me until March 2021 to find the right department to cancel the flight at get a refund at Airlink. I have been waiting since March for my refund. It was said that it will take 4 months to process the refund but still no success. Who takes 4 months to process a refund? I leave messages, send emails and I just auto replies back. When one manages to get hold of a staff member, the responsibility is just passed to the Refunds department, who just does not reply.
