Assuming US, https://help.ticketmaster.com/hc/en-us/articles/964220803278... says:
“To find the instructions on deleting your account, select “Your Choices & Rights” from the Quick Links menu on our Privacy Policy site and navigate to US rights.”
Doing that gives me (on https://privacy.ticketmaster.com/privacy-policy)
“You may enact any of the above rights by submitting a request clicking here* or calling us at 855-663-0150“*
“Here” is a link to a page that appears to allow you to request your information, correct it, or close your account.
You could update the account with incorrect but realistic information. As a last step, change to a throwaway email address. Then just abandon it.

I'm sure there is a fee involved.
It was very difficult to get my Ticketmaster Account closed. VERY DIFFICULT. I will never do business with them again. Writing a letter worked … info follows:
I tried calling Ticketmaster at 1-800-653-8000 … this failed.
Eventually, I was told I needed to write a letter addressed to:
Ticketmaster - Fan Support 1000, Corporate Landing, Charleston, WV 25311
Subject Line: Request to COMPLETELY Close Account and delete information for [Your Name]
To Whom It May Concern:
Please completely close my account and delete my personal information with Ticketmaster. My account information follows: etc.,
NOTE: It took two months, but eventually my account was closed and the information was deleted.
I wish you good luck and hope the above information is helpful, I would love to have understood what I needed to do from the beginning.
