Christ University — Consolidated mark sheet and transfer certificate

I graduated from Christ University, Bangalore (Central Campus) in the year 2020. I did B Com Finance and Accounting and my register number is 1712243. Earlier in 2020, due to covid we received our degree certificates through courier. I received only my degree certificate in the folder and not my consolidated mark-sheet and transfer certificate. As this is my first degree, I didn’t know what are the documents we were supposed to receive. Now when I’m applying for my masters they asked me for my consolidated mark sheet. and I asked my friend if she received one and she said yes. So I sent a mail to office of examination and the replied back with a number and asked me to enquire on this number. I spoke to a ma’am on that number and she was very rude. Later she gave me another number and that person told me you should ask the ma’am we have no idea. So I called her back and she was very rude to me the whole time and said she doesn’t know and hung up. The other sir asked me to come down to the college. I stay in Coimbatore and I have very bad health condition and have been hospitalised for a month. They haven’t been cooperating at all and are very rude. Now I can’t apply for my masters either without the consolidated mark sheet and my deadlines are nearing. I can apply for another one and pay. I just want them to guide me through the steps and not be very rude.
