Blue Dart Express — delivery man not attending his mobile

Address:

Chennai, Tamil Nadu, 600097

Hi,

Today i received a package via bluedart which is ordered via amazon site last week. Actually i was not available to receive the package.

The delivery man sent me link for payment since i made cod.. Due to my unavailability he shared me that link.. He then called via this number [protected]

I direct him my address, he said he kept on my doorstep.. But i can't find my parcel when i reached there.. So i was trying him to call for the place where he delivered

Please help me with this
