University Of Calcutta — Not Getting Marksheet From my college

Sir/Madam
I am Pallabi Roy. I am a Student of Bijoy Krishna Girl's College, Howrah of Bsc science general (microbiology, zoology, chemistry). I had appeared in Bsc supplementary examination in Chemistry (part 2) which tool place in Nov-Dec 2020 in OBE mode. the result was declared on 12th January and marksheets were handed over to the college on 15th January (as per CU notice ). they were giving the result for 1 week, but i was unavailable at that time as I am out of station for my Msc classes. After a week my Parent's went to collect the report card but they are making excuses and saying the office is closed. My parents went there for 3-4 days but everytime they use to say that the office office is closed due to various reasons. In this way they are harassing the students by not cooperating with them. They kept the office phone line dead so we cannot call to college office and contact with them.
Please look after this issue as I need my report card very urgently for my M.sc. I need my report card urgently for my document verification in masters.
Please take some quick actions as soon as possible
