National Board Of Examination — payment hassles for neet-pg 2018

My candidate id is [protected]. I applied for neet pg 2018 entrance exam for md/ ms but could not complete my registration. For payment option i paid rs 3750 three times using the pay by card option, by indusind bank on 23/11/2017 at 15:16. Total amount of rs. 11, 250 (Three failed payments) was debited from my account but the nbe website showed "payment failure due to exception" option and i could not proceed further and select the test centre.

The website shows payment cannot be done due to an exception.
This way i lost rs. 3750 thrice i. E, a total of rs 11, 250 and i could not do anything. I am worried coz the form filling deadline is in another 3 days.
I request the responsible officer of nbe to kindly help me in urgent basis as the nearby test centres are filling up first, and the deadline is just three days away and kindly refund my amount.
