Gati-Kwe — Missing package and no action from Gati

I booked a shipment from pune to kolkata on 8th feb through First choice movers and packers, who have booked a shipment with Gati. The assured delivery date was 17th feb but it got delayed. Finally, on 21st feb it said that only 3 out of 4 packages have been received at destination hub. Then it called that my package have arrived and said that they have sent it a different address even after confirming the pincode with us. And then simply returned it back to Kolkata hub. After that as i called again to customer care, they are saying my one package is still missing. All this from 21st feb to 7th march and no action taken from Gati's end. My 3 packages aren't delivered yet.
