Ask HN: How to Delete a Ticketmaster Account?

Hello, after recent issues with TicketMaster, I was going to delete my account. Maybe I'm missing something here, but I'm unable to find how to do, and the only option I see on their support is "send a letter to <address>". Isn't this one of the worse and most offensive dark patterns that exists? or in the digital era, this is in someway justifiable?
