I have a .co.in domain with Rediff. They did not ask any KYC documents though. The domain name was bought using a credit card and the whois showed my real name, e-mail and home address for a while before getting redacted. Ofcourse the replaced my phone numbers with theirs to prevent transfer of domains.
Renewal of the domain is now done using UPI.
Do check them out as well. You can get someone across on a phone if you leave a callback message.
