.I fee for you and do acknowledge that postal office staffs are involved in many unlawful acts ranging from opening of parcels to demanding money. your wrote "This week I had send some stuffs in Nepal through usa's postal service to nepal's address". Did you mean, you sent a camera using USPS? If No then follwwoing may not be appropriate commet for you. If yes, Then you went against the Prohibitions of USPS on the first place. Please read this USPS page Camera is listed as prohibited item to send to nepal. And if you send any other valuable articles you should have filled the custom declaretion form, even if that was a gift. When you sent something without declaring the items you sent and against the rules, thent here is nothing you can complain about.
