Use @BSNLCorporate on twitter for raising BSNL related issues. It works. And for subscription activation, you need to install yupptv first in your registered mobile and open individual OTTs from yupptv app to get them activated. After activation, you can open the OTTs even without yupptv. Lionsgate requires some emailing, twittering with both lionsgate and bsnl. That's what I've done to activate all.
