Tradus — Not recieved Full order

Address:

Hyderabad, Andhra Pradesh

I have ordered a product of quantity two.
In Tradus my status is Displayed as Shipment Delivered to the Sub Dealer.
but what i have received is only one pack out of two packs.I have Called the sub dealer(Onetomany) and the response which i have got was it was there mistake and i will be getting my remaining order in 2 days but later they stopped answering my call.
Then i sent mail to Tradus but they didn't reply yet.Now it has been more than one month and still my complaint is unattended.
