Hi,

I ordered/imported one iphone 5s from one well reputed seller. Today i received parcel today but that parcel was very light weight, and the packaging was not as it usually packed. It was just an empty box.
After open the box, i found nothing inside the box. Box was opened and someone who shipped the item stole the iphone, and then packed it again. While checking the box, it looks the box was opened and then packed with tap again.
If some from indian post start stealing the item, then i don't know whom to trust.
Its really pathetic. I was waiting for almost 3weeks for the product. I do not see any system in indian post, who can track the complaints and take action against those insiders thief's.
