National Board Of Examination — unable to complete the application for neet pg due to payment problem

In the process of filling the application form for neet pg 2018, the second step has been completed while making the paayment i have tried four times and the amount (Total of 12, 000) has been deducted from my account all the four times, but the nbe site shows the payment process has not been completed and im unable to proceed. As today being the last day for filling the application i unable to proceed further and i can not afford to lose another year. Very much disappointed with nbe. Kindly look into this asap.
