You might be able to just beg. I had a frustrating experience with the YMCA a few years back with their cancellation flow requiring you to physically show up with a signed form and I called telling them I was trying to cancel because a spine injury made it impossible to work out and rather difficult and painful to even move, let alone travel to the YMCA, and they got a manager on the phone who canceled me after saying it was acceptable to take a photo of the signed form and e-mail it.
There's at least some hope of decency and empathy in an individual person empowered to override process prescription even if there will never be any in the dark patterns dreamed up by the corporate-level customer retention team.
