this is the exact same issue I have. Trying to get the travel voucher isn't proving to be so straightforward. I'm now upping the anti and increasing my email and call frequently each day until I get the voucher!
interesting I was under the understanding that the Thai travel vouchers last until December 2022 for rebooking? I'd be interested to know if you can indeed get a refund from Thai Airways directly - my communications with them so far pass me back to the travel agent and can't seem to offer me much help as I didn't purchase the ticket through them
thanks Ross, this March it would have been 2 years. Driving me crazy tbh as I'm being told by Thai Airways that they can't issue me with the travek voucher and it needs to be done via the travel agent. The travel agent however says that my ticket has now been purged and I can online deal with the Airline directly
