Hello,
As ING Vysya Bank was merged with Kotak Mahindra Bank
The entire assets and liabilities too were merged with Kotak Mahindra Bank
So - for NOC - you have to visit Kotak Bank Retail Asset Branch along with
> Copy of RC
> Loan Agreement Statement or Loan Account Number of ING Vysya Bank
> ID Proof
to make a request to issue NOC
Hope they will be able to extract loan details through internal software to issue NOC accordingly
