I am facing payment issues while registering for my sister for norcet 2020.
While registering i selected "payment options #1" the payment mode i selected was sbi netbanking and proceeded with it the amount got deducted from my account, due to some technical issues the payment wasn't successful then again i tried to pay via "payment options #2" (Bill desk) the payment mode i selected was upi then again the amount got deducted and the payment was unsuccessful.
