May I request you to be little polite towards fellow members, especially the newbie ones?
@juggu123 has shared Assam Nodal officer details only. As we can check from the full screenshot above – Assam, Bihar, Jharkhand, Odisha, West Bengal are having the same nodal officer.
The same you can cross verify on the official Sun Direct website:
Sun Direct Nodal Officers
Why do you think one nodal officer can not manage multiple regions? Brands does it to cut down costs, Airtel also does the same thing for their
Broadband Appellate Authority.
You should apologize for showing unnecessary rude behavior towards juggu123 who only tried helping you by providing the relevant information. As the conclusion was he has provided correct info.

Even if someone provide wrong info by mistake, we need to be more understanding considering it's done on a goodwill and voluntary basis.
