[Resolved]  HDFC Bank — reg: selling personal information

I have recieved some call from some people "as they are telling that they are from npci" and they have recieved the complain that my policy which has done through hdfc life has given policy by telling lie. Which was actually correct & the same.
Regarding that i have written earlier so many complains to hdfc but didn't get any proper response.
Now again i am receiving the call. I don't know that they are really from npci for helping people against fraud or they are cheaters who get the information from these company or their authorized agent (Because they only have such secret information).
I got the call from mr. Pc dubey bearing the mobile no. [protected]
