Visvesvaraya Technological University — issuing migration certificate

I have applied for migration certificate by post on 22 aug 2017, it was received at vtu on 28 aug. But till now i haven't received yet, i called many times to vtu office and even mail them but so far no response. I asked one of my friend to go vtu and find out scenario of it. She went on 23 sept but they had not made certificate yet, when she asked they made and gave xerox of it to my friend as per vtu rule they won't give certificate in hand. So she asked that person (His name is krishna) to send it as soon as possible. But till now i have not received any thing. If they have so much problem in sending certificates then they should change their rule & start giving migration certificate in hand of concern person.
