Couple things, it might sound silly, but did you receive the invite for this Org? Via email or in your Dashboard? Secondly, if that Org was created in a different region than your Dashboard, which it sounds like it is, that might cause a problem. I think that is only isolated to China though.
Maybe ask the India Org to take a screenshot of your provisioned account to ensure there are no typos in your email address and to verify permissions. If that doesn't work I would open a ticket with the Meraki team to rule out any back-end issues.
