Paynimo / Techprocess Payment Services — transaction failure: seeking refund

I was trying to make a payment from my pnb savings account (A/c no. [protected]) to make payment of my wards tuition fees through your techprocess gateway, payable at vit, vellore.
However, the transaction did not complete successfully but the amount has been deducted from my account.
The transaction details are mentioned as below:

Transaction remark: techproce/[protected]/[protected]
Punjab national bank savings account number: [protected]
Transaction amount : rs 4, 69, 782.70

I request you to kindly look into the matter and initiate my refund as soon as possible. It is also noteworthy that i have faced the same issue through your payment gateway on 19/06/2020, it seems that there is some problem with your gateway for payment of tution fees at vit, vellore.
