Travel Triangle — Fraud and cheat company

In late august 2021, i have booked a maldives tour from travel triangle. And after a week of payment for first instalment, crafts holiday agent called up and told us that the hotel is fully booked and we cannot book it.
They informed us about this after a week.
When i asked for full refund they said that only 50% payment is refundable.
I haven’t paid them for discussion of the hotels.
They are not paying the full amount when the issue is at there end. If i would have cancelled it, i would have not asked for any refund. But when they are not able to book the hotel even after the payment, they should refund full amount.
After continuous follow up, they are still not replying to any of the mails.
Moreover, just before a week when the travel was schedule, agent called up and said that the rooms are available but at very high cost. Please confirm the booking as the previous offer was only for August month. I have completed the payment on 29th August. If the booking deal was till August, then how the resort is not booked and before a week of travel, resort is available but at higher cost.
Now travel triangle is not giving refund nor booking the resort even when the resort is available
