I have booked a sikkim and darjeeling tour from Destiny tours and travels, gangtok. Mr. Bikash gurung is the person, as on the last day of tour our hotel was not booked also the vehical for transporting to airport is also not booked. As I already made the full payement towards the tour cost still agent didnot book for last day and tried to reach on his mobile but coming switched off. So I made my own arrangement for last night and also for transportation to airport. When I talked with him next day he promised to give me money back for the all inconvenience caused on last day. Total amount to be refunded is 14500/-. But now he is not picking up the phone. I dont know what to do aur how to register complaint. This tour have very good website and seems very trustworthy at the start but at end it was not good at all. I live in nagpur and cant go to gangtok to register a police complaint. Please advice. Contact no of agent: Bikash gurung, 8906237451.
