[Resolved]  HDFC Bank — Personal Loan not honoured- confidential documents leaked

Address:

560085

Applied for personal loan with HDFC bank with loan reference number:41466604 on 1st Aug 2016 in BANGALORE.
Submitted all documents including 4 blank cheques as security.
After few verification, the bank employees informed over phone that my loan request got rejected.
I have not recieved formal communication regarding the same.
I mailed to saubhagya.[protected]@hdfcbank.com and an assistant Manohar with phone no: +91-[protected] asking the same was in vein.
The documents are not returned to me back.

However, the bank employees have not kept the confidentiality of the loan application and leaked my details with other banks.
I have been getting frequent calls for personal loan from other banks saying "your application is being rejected by HDFC. We offer better rates with no pre-condition" .
This is a serious offence.
How, does such confidential information gets leaked out of HDFC bank?
Why the bank is hesitant to give the confidential documents that i submitted? I heard repeatedly that only blank cheques will be submiteed back.

There is no response from the bank.
Only a bunch of people who are like sales agents would answer the call only to delay.

Can i file a criminal case against bank for such breach of conduct?
Who fixes the accountability of banks in this regard?
What penal action would be taken against bank for such breach?
