Billing and account issues

We are locked out of our account as the email associated no longer exists at the company. So we have no “recovery” option, can’t log in but keep getting billed. Support seems non-existent and the phone number listed for billing is a disconnected number. I’ve tried submitting tickets (irrelevant replies such as password reset), emailing support (unmonitored inbox return), calling (number is disconnected). This needs a human, not a bot but there doesn’t seem to be any way to contact WebFlow anymore. Any suggestions welcome!
