Bangalore University — not issuing photocopy on mentioned date and not receiving calls

Respected sir/mam,
I am a student of 1st year bca, my college is affiliated to banglore university,
On 13/07/2020, the university released notifications for revaluation and photo copy.
I applied for the photocopy, as mentioned in the notification circular the university was supposed to be issuing the the photocopy to us, through their online portal, on 2/08/2020. But it failed to do so.
I have been trying to contact them regarding this, but they are not receiving my calls.

Whenever i trying to call them, i am getting the same dial tone, as the "person you are trying to reach is conversing with someone else please try again latter", i`m getting the same thing irrespective of time. I. E every time i`m getting the same thing, which seems that they made to hear this tone whoever calls them, ([protected]) this is the number the banglore university given to contact regarding revaluation matter. And things related them.

Initially after checking my photocopy of my exam paper, i intended to apply for revaluation.
But since the university failed to upload the photo copy. I am not able to proceed any further.
And moreover 7/08/2020, is the last date to apply for revaluation.
If i don`t apply then, i have to pay 250/- as fine along

I approach here with the hope of getting my problem solved, kindly please look into the mater.
And take actions soon as possible.
