I have ordered 02 seagate harddisk and 02 ambrane power banks on big billion daye from 02 oct to 06 oct, but all the orders they have cancelled mentioning the reason that the pin code is not in service area, i want to say that the same thing they would have informed during placing order or they would have sended message regarding this, i would have given any alternate. The product was on discount but now it is available without discount and ther are keeping me in loss if they are not capable to do so then why they are taking orders or they accept the pin code during placing order.
