Refund issues, poor response, money paid 18months ago!!

I am getting no response, my travel agent is not getting response in under a week. I booked an expensive package for Mauritius and paid BEFORE lockdown. This is now 1.5years ago. Club Med kept my money and I now cannot travel due to vaccines. I need to get a refund ASAP and not in several weeks from now. Air Mauritius is under business rescue. I booked both via Club Med and now cannot get my money back.
