Amazon India have no author central. The staff respond to messages and direct you to edit their site by contacting Amazon US, who are absolutely useless at making updates, as such no updates are made on any linked site. There appears to be no way of updating the listings. Their information is not a reflection of the other Amazon sites. If your listing is incorrect, it is highly unlikely that you'll be able to correct it, therefore it is highly unlikely that you'll sell anything on there. I rate them above one star purely for responding to messages and being polite when doing so. I am unable to comment on the remainder of their services or in any other respect.
