How to exit counselling?

so I want to cancel my COMEDK counselling because I am pretty sure that I will not get a seat in round three, and I haven't been allotted any seat in round one or round two. I don't want to go into round four because if I go into round four and get a seat, I will be forced to take it. If I don't take that seat, I will be forced to pay a fine of around ₹13 lakh or ₹14 lakh. So, how can I exit the counseling process in round three itself?
