HDFC Bank — Amount transferred to unknown account

I had HDFL Life policy Number 15489275. There was a pending amount that they should have settled. I had received an email saying the amount has been transferred to my account, which i saw today.
As i had not received any amount in my active ICICI account, i called the customer care. As i spoke to them i got to know that they had transferred the amount to BENEFICIARY account which is my wife Veena S. I asked them which bank they said HDFC. But she had never opened any account with HDFC bank.
Further when i asked they said they have the UTR details and i should check with all the accounts that the beneficiary has. which was not possible as she only one account with a local bank. When i asked to talk to the Manager she also mentioned the same. As i asked her repeated to get the right details she disconnected my call.
