The Professional Couriers — products opened and damaged, another not delivered

I had couriered 2 parcels, on 25th december vide consignment # pon7918654 & pon7918655, where 8655 reached against pickup at destination, all the edible items packets were opened and consumed during transportation, materials reached opened approx less than half quantity (Against their quality policy). Another one 8654 still on hold at balia office for pickup. Now my complaints if i paid full money for courier charges, they are responsible to deliver the product timely and safely, instead they are threatening that if you dont come to pickup 70 kms from destination they will return.in this case do they return my charges as well with the product or not. Its a total case of cheating and disrespecting the courier policy. Such cases must be addressed well and this kind of couriers must be closed down.
