Those who had taken loans from HDFC Bank.Please keep in mind that even a single cheque bounce would result you in having no loans from other banks in future. Even if you had settled your loan amount in full, they would always point out the single cheque bounce and deprive you from availing any through their mails sent to cibil. Its happen with one of my friends.
Not just that, if the emi is not paid, or the credit card payment is not done, they will transfer it to collection agents and those collection agents will have full access to ALL HDFC accounts no matter weather the account belongs to the borrower or not. this raises a serious question about the safety and confidentiality of customer’s account information. those can me misused!
