I have already raised the issue of non receipt of certificate one email. The response email received instructed me to call the number 88811 97198. When dialled the number which was focussed to serve the sales query instructed me to raise the query on the forum.
I strongly recommend for a more efficient grievance redressal mechanism. While the certificate query seems to be generic at the first sight, its a query specific to the user.
I request you to kindly look into the matter.
thanks and regards!
