I see there's others having the same issue, the only thing I see connected to my accound in https://www.atlassian.com/purchase/my/ are two subscriptions for bitbucket but I cannot do anything with them. I cannot cancel them or anything. I'm not paying anything for them, they're from decades ago, I don't remember if they were company related back then.
https://admin.atlassian.com/ won't open for me, tells me to create a new org (I tried that and didn't find anything, deleted test org afterwards).
https://bitbucket.org/account/workspaces/ there are no workspaces here either.
I tried this GDPR deletion form https://www.atlassian.com/trust/privacy/gdpr/request-delete-personal-data but that sends me a link to the account page where delete is not working.
