We have referred to the postal department about the situation. The post office replied that there were two possibilites: 1) the parcel was lost or 2) it was retained by the Custom and Excise department.

Since it has exceeded the normal delivery time, it seems very probable that the parcel was lost and we therefore refunded you all the charges.
