Hi to everyone.
Guyz im selling used mobile thru Ebay.
I use Blue Dart to courier the goods. But sometime they refuse to deliever to some places. Like recently they refused to deliver in Bhubaneswar(Orissa).
I want to know What should i do in that cases.
Should i use Indian Postal service?Is it a safe method to deliver?
Or can you guyz suggest me any other safe n reliable courier
