Any way to upgrade my choice in Kiiteee counselling?

Guys anyone who gave kiteee and have got 2nd or 3rd choice and wanted for upgradation are they have options to upgrade?
I got an email from Kiit in my father's email id that after first round counselling there will be an option for branch upgradation but second counselling result also published but no option and tomorrow is final allotment branch date for 1st round counselling. I am thinking now that in Cs branches there is no upgradation available, am i correct?
I had got Csse , i am happy but father told to upgrade if possible.

Try mailling them

Today i got allotment letter now so basically no upgradation available maybe after starting of college option may be available.

Will college start before Mains?

Yes starting from first week of September.
