Bluehost India discontinued its Affiliate Program recently. If you were promoting them, it is time to change the links to another host may be Hostgator.
Bluehost India was a fraud company anyway. I registered for their hosting once - I uploaded my sites and my sites stopped working in 3-4 days. All the files were deleted on the server. When I asked the support, they wanted me to upgrade my account to their backup services. I tried to cancel my account but their system would not allow you to do that. It was waste of money.
You say another company "Hostgator", but I think they are both owned by the same group. No idea about Indian market, but probably a strategy for them for focusing on a single brand etc. If you are unhappy with one, you'll most likely be unhappy with the other too. That one is an opinon, not experience
Both are owned by the same company. If they stopped it for one chances are they are going to stop soon for the other.
