outlook recovery form keeps getting rejected, is there any human to talk to

Double check the address you're putting at the top of the form. hotmail.com, outlook.com and live.com are separate, and an old account can have an alias you forgot about. Getting that wrong means every answer is checked against the wrong account and it fails no matter what you remember.

For a free Outlook.com account there isn't really a human route, support just sends you back to the same form. So the form is the thing to get right. What helps: fill it in on a computer and wifi you've used that account from before, because they weigh that. Put in every old password you can remember, even ones you're unsure of. Exact subject lines of recent emails you sent and the full addresses of people you emailed count for a lot. Use a contact email you can actually check, since the reply goes there. There's a limit on how many times a day you can submit it, so don't fire off five rushed attempts. One careful one a day, adding a bit more each time.
