Hi my parcel from china has reached kolkatta and its still there for the past 10 days, please do something to release my parcel, i guess its lost or its being not updated in the system, its a registered air mail so for sure it has tracking . package contains two boxes of led light, very small ones used for cars. it should have been delivered long back but still its in kolkatta, so make it get delivered soon
