Nagpur University — delay in transcript issuance - asking bribe

I have been chasing to get my university transcript for B.Com from Nagpur University for last 1 & 1/2 year. I have paid nearly Rs 8000/- to the person next to Mr. Pandey in Degree section, other than the fee for duplicate and transcripts for which i paid nearly another Rs 3000/-. Till date every time i call the person he makes some other excuses and has not provided me the transcripts yet. He has taken the originals as well saying that there is a correction needed. I am now tired of chasing him. Every time i call him, he tells me a new problem, saying there is a mismatch in marks or name and needs to be modified. I had submitted Transcript request on Dec 23rd 2017 and till today I have not received my Transcripts (2nd & 3rd year BCOM + Degree). It looks he intends to ask for more money. I also said whatever money he needs i will pay but he is still only delaying further.
