Did you get hold of any shipping documents from them my pal? If yes, then you have a case against them. If they were shipping your consignment by sea, you may be able to find out the status of your shipment by contacting the agent of the shipping company or the airline if you were getting the shipment through air my pal. Have any of your colleague or friend in Doha call on them to find out the status my pal. Hope this works out in your favour my pal.
