Mumbai University — Not getting Sem 6 Marksheet

Due to the revaluation issue, I didn't receive my sem 6 Marksheet. I then went to the Kalina Campus to submit all my marksheets from sem 1 to sem 5 in the last week of december 2020.
I was told that I'll get my sem 6 Marksheet by Jan end 2021.
It has been more than 1.5 months I haven't received the same.
Also I have been trying to contact kalina campus daily on their number 26543300, but no one is responding.
I need my marksheet as soon as possible because I have to apply for further courses.
