i got new i phone 6 seal pack but it have a no original charger head set sync cable why?

Probably because it wasn't really new. It's a trivial matter to shrink wrap a box.

Take it back to where you bought it.

If you have the receipt or any evidence that prove you have purchased this device, you can ask for a refund.

Tell him then you don't want it without EarPods, Lightning Cable and USB Charger.

Also make sure Find My iPhone is OFF.

I would call it fraud.

I was once in the back section of a major discount retailer (name withheld to protect the guilty). There was a department with a shrink-wrap machine. All returned merchandise went to this department, where they cleaned it up to look like new, and shrink-wrapped it.
