On Jan 8th, i went to Phoenix from LA, I did not get my package there.<br /><br />I reported and left a message about my info, and I got a message from the navigator that the package will be arrived tomorrow night, but i didnt get it. So, I called again and said that I didnt get it yet but they said the post office and its postman were not able to communicate to talk about the case and said they will call me back later. After, I called and visited few times but they kept saying samething. There were no way to stay longer in the U.S. and returned to my home.<br /><br />After retuning to my home, I left a message to wheresmysuitcase.com that I've lost my package for almost 1 month and have not gotton any info about it at all. And, it affects to my besiness extremely bad. This is not understandable happenning and very uncomfortable about the case.<br /><br />There were so many difficulties while visiting the U.S. and still waiting for my important documents in the package.<br /><br />I wish I would get my package as soon as possble desperately. Please help me to get it soon.
