Ticketmaster keeps ignoring my request for a refund for Calabash 2026

I had tickets to attend Calabash SA 2026 but the event was cancelled. After waiting the allotted time for my refund, I submitted a ticket with Ticketmaster support requesting my refund, but they keep closing my ticket without addressing anything. The only communications I get from them regarding this is a survey asking how their support service was. To this day I haven't received my refund for the concert and am being ignored
