I received an two emails from ticketmaster saying that my voucher which was used for a cancelled play, was extended until 2022. When I recently tried to confirm this again, I was told that the voucher expired 2020 and I could no longer use it. The issue is that ticketmaster told me it was good until 2022 and so based on the information they gave me, I believed it was good until 2022 and had time to use the voucher. They refuse to acknowledge this even though I sent them proof of their emails, and keep reverting to their argument that the voucher expired in 2020.
