Like I frequently¹ advise²:

Don’t look to large, well-known registrars. I would suggest that you look for local registrars in your area. The TLD registry for your country/area usually has a list of the authorized registrars, so you can simply search that for entities with a local address.

Disclaimer: I work at such a small registrar, but you are probably not in our target market.

I miss the days when Network Solutions had a permanent option to switch/sign-up with a PGP key, binding all future communications and change requests to it.

I forget how they handled key expiration/revocation...
