I had tickets for Ringo in June- now postponed to June 2021.
When I checked my tickets on the TM site, there was a refund button- all you have to do is click it and your refund, including all fees, goes back on your cc.
Good luck!
It took over 30 days to receive mine. I did notice language on their website that says certain events could wait to see their refunds until up to two weeks before the event.
