KYC UPDATE and HDFC BANK STING OPERATION

After a report of sting operation where HDFC bank alongwith other banks involvement, the HDFC bank, it appears,  has asked unnecessarily to all existing customers to submit fresh KYC compliances.  The reasons
given are that … You KYC update is due and hence provide documents by date ……  ..(a very short notice).  When does the KYC update fall due for renewal ?  It’s a question mark.  What the bank wants to prove – there is another question mark.
