I've been trying to delete accounts at Anthropic and Cursor because they don't let you change email addresses (don't even get me started on that stupidity). But until my subscriptions that I've cancelled run out and/or the final billing is done, I can't actually delete them. I can't just forfeit the remaining time on my month's subscription, I can't force them to bill me and shut it down, and nothing I do gets me where I can ask a human to just shut it down. I also have no option to remove my billing information in case someone gains access to my account under my old email address, which is trivial to do.

I honestly think I'm going to have to cancel my credit card and get it replaced to accomplish breaking that connection with those two companies.
