Hey aspirant

Hope you are doing well. You only have to pay 35000 INR only if you get a seat in JOSAA. But I think you have withdrawn from the counseling. Now if you have paid it, and did not get a seat, refund will be initiated in some time. Your bank information must have been taken at the time of registration therefore you need not worry, if you want some answer then you can mail them at csab2021help[at]mnit[dot]ac[dot]in.

Hope this helps
