Hi My Name is Rajesh Kumar i have passed my MCOM finance in December 2017 .I have not received my Original Marksheets and Degree Certificate.When I contaced them Through Email they showed me the Screenshots that they have dispatched the marksheets through post.But i have not received anyone.
And now as i have requirement for my job purpose when i contaced them through mail they said that Rs 900 rupees will be charged for Each Marksheet .

And Rs 1450 for My Original certificate.But My concern is why should i Pay them when it is my right to Receive My marksheetr and Certificate without any charges.

Please help me with this issue.
