Sir, if you dont mind, the only solution is to simply say NO, thanks, i dont need lone and close the case. in case they pester you again , just ask for his name and you have thephone number., and send this info to support@hdfcbank.com with a strongly worded compain. the person who called you cannot be an employee of hdfcbank, but a staff of the Direct selling agent of hdfc bank. the same thing happend to me, i complained to this adress and after that all such calls stopped., this was about three years back

Pls confirm it again with bank..................................

May I introduce myself as a retired banker? Mehtaji, banker's as policy would not do so; so far as SBI is concerned. Other banks might hv gone so down, is not intelligible. No such telephonic information must be given significance. At the most you can call back the Chief Manager, or Asstt. General Manager, whatever grade br.it, about any such calls emanating from their end. I doubt these are found players. I had an email message that I had been chosen by a Yahoo survey on lottery basis as a winner of 7.5 crore rs. for which they wanted all my personal details e.g. a/c no., home addr. name of city etc. I replied them to tell me how will you make the payment to enable me to decide whether I should send you the required information. They did not reply.
The gist is, be ware of such allurements.

They knows it very well that once the customer says yes they will earn money like any thing as there for taking payment customer will come to them and than they will show there real colour to the customer

Dear sir Beware of these Bank people , what they say before it will not be the same after becoming the customer:
They are just like politicians , vo jo milte the kabhi hum se deewanon ki tarha (before election)
Aaj yun milte hain jaise koyi pehchan na thi (after election)
Their hidden charges they dont declare and they are not fully transparent
