I couriered my letter on 6th january 2020 at koppal karnataka to bangalore but it did not reached till now. When i call customer care service they are telling that the parcel has missed out and they are unable to trace that, but the status in their website is showing that it reached to bangalore but did not go to delivery address and showing in transit status. I have been complaining them for 3days they are telling that the issue will be resolve but till now no progress.
