Bajaj Allianz — Not received the amount/cheque after surrendering the policy

Address:

Bangalore, Karnataka

I have taken policy in Bajaj allianze ( Policy number [protected] and [protected]) and surrended it on 18th Jan 2011. Still I have not received the amount. I called Bajaj Allianze Jayanagar branch and not got any proper update or responsible answer for not getting money. They are telling they sent the cheque through over night courier on 4th Feb 2011 and given the contact number and the consinment number[protected]. I called all over night courier numbers but not able to trace where my cheque is laying and when I will receive that. As it is a local courier delivery (Bangalore Jayanagar to Bommanahalli) it should come on the same day. Please help me in this regards. My contact details are :
