I worked with HDFC Standard Life from January 2007 to July 2009. I resigned and joined another company. I did not receive my relieving letter from HDFC SLIC. Recently, I have been selected for HDFC Bank and they now require the relieving letter from HDFC SLIC. I have contacted the regional HR, but their responses have not been satisfactory. Kindly advise on how to obtain the relieving letter from HDFC Life.
