I would like to escalate the issues i was sent a courier 28th of dec from ambature ot courier office unfortunately time delayed they said we will pass it to the next day 29/12/2016 we accepted. The courier weight is 1.8kg while we sent from chennai. But we received the courier 31/12/2016 we got a surprised there are lot of things are missed in the pack then we check the weight it shows less than 1.0kg. We called delivery boy mr.
