Trackon Couriers — Shipment not delivered and not returned

Address:

Palam Vihar, Gurgaon - 122017

I had couriered the important documents through Trackon (Consignment No: [protected]) on 7-Oct. Firstly it is not delivered mentioning area is not serviceable. Why they accept the shipment and charge if area they don't deliver.
Worst part is return part. They kept the return with them not returned back to me. I have to go to there office and collect it. On asking they should have returned to return address mention, they told no. They don't return it. They started miss behaving with me. Strict action should be against this type of fraud companies.
