Address:

Hi Sir,
My provisional certificate number is[protected]. While applying for OD after payment of 600/- and money debited from my account I have got internal server error page. So I tried again doing the payment and this time also got the same internal server error page. I contacted the student support number and they said that the payment status will be reflected after 24hrs.
I request you to refund my payment of 600/- that I have made the second time. Please find the attached screenshot of money debited messages for reference. Please do the needful.

Thanks
C Mahesh
