PS I agree with the previous post regarding the companies "offering the visas". No companies are authorized to issue India visas. Only the Government of India issues visas. The companies only offer to help submit the application, and with electronic visa application, it is easy to DIY.
If this is the same OP from a previous issue, his flights are on separate tickets and therefore he would have to get a visa no matter what or be denied boarding to MAA in the first place.
