I had a long email discussion with Namecheap and they said that INRegistry is the one to blame. Now INRegitry said opposite of what Namecheap said. I am seriously confused which of these two are wrong. One is wrong for sure.
Update:- Looks like INRegistry and Namecheap will communicate directly.
That's right but their email response says that they and their all registrars hide sensitive information. When I checked manually, most does but not Namecheap. Even if Namecheap does not violates GDPR, Namecheap still blamed registry while registry says otherwise.
