Trav Bond with office at Mayur Vihar New Delhi - Hotel Bill amount not refunded by Trav Bond

I booked a *N *D tour to Hong Kong from ** jun ** to ** June **** through Trav Bond company having office at C**, Archaya Niketan, Mayur Vihar New Delhi at RS *****/-. The package included hotel accommodation at hotel Silka, Tsuen Wan, Hong Kong. On arrival Hotel said that our agen t has only booked room but not paid any money. If we want to take the room we shall have to pay at our own. I immediately contacted Trav Bond who expressed this a mistake as hotel did not agree for some payment mode. They also asked us to pay , which they agreed to reimburse on return. We had to organise cash in HK dollars ( ****.**
) and paid . After coming back have written to Trav Bond a number of times , but they have not yet paid the amount. The company is clearly a Fraud . I seek this amount refund from them. Can’t explain the amount of harassment we had to face at new country with no fault of ours.
