Rediff.com — non delivery of products and refusal to refund

I bought two hanging mosquito net on 3rd April 2015 from rediff shop. the consignment was despatched on 7th April through firstflight (Consignment no J[protected]) and on 10th April rediff shop mailed me that the item is delivered to me. but i have not received the consignment. The first flight Imphal has not received the consignment so how can it be delivered to me. Online status of the consignment is "In transit". So on what basis rediff is telling me that the item is delivered. In my rediff login the item is marked as delivered on 10th April, 2015, 08.42 am. Where is the proof of delivery then? who received the item? Rediff has no information and they never reply to my mails. Ironically no office, private or public is open before 10.am in Imphal so the item can never be delivered before the working hours. i have been writing everyday to rediff but no answer till date. Again the item was shiped on 7th April, so it can never be deliverd on 10th April due to remote location of the destination (Imphal). So rediff is a fraud company
