Railway Recruitment Board Payment failed due to session Time out and account debited twice

Hello RRB,

I have applied for Railway ALP Post on 31st Mar 18. My Application webpage got session time out after I completed Payment for fist time, but payment of rs 500 got debited from my account.
I visited again to Railway ALP Application page and checked the Payment status, it was still pending/Not paid. So I did it twice and this time it happened successfully.
Kindly process my complaint to reverse the additional amount paid of INR 500/-. Below are my Account details:
