Expected date of delivery was 04th Oct. today on 5th Oct. i didn't received my order. why the delivery details has changed now its shows delivery date on 07th Oct.
I don't know why this happening?
I pre planned all things like my train tickets for going to my village gift someone etc.
But now all changed just for delay in Delivery. So please give me my item as soon as possible and also pay charged for delay in delivery.
