ticket cancelled by nusatrip & no refund after 45 days

NO MONEY REFUNDED TILL TODAY INTO MY ACCOUNT. NUSATRIP SAYS MONEY REFUNDED ON 27/07/2015. IF REFUNDED, PLEASE SEND PROOF OF REFUND. TKS

I booked ticket with booking no. 81F71M from Paris to Iceland. After my credit card was charged, nusatrip did not even inform that the airline cannot issue the ticket and the transaction was cancelled without notice by nusatrip. It is totally a DISASTER as i have booked the hotel at destination but no airlines ticket as the ticket is cancelled by Nusatrip and my whole holiday trip is ruined.
I have to purchase ticket at other online venue at much higher price. Is this the reason that nusatrip cancel the ticket cause the price increases?
Nusatrip promises to refund the money. After a month passed, the money has not yet been refunded. I asked for proof of refund without any reply and was being thrown from one person to another person when i called the company. I feel being robbed and feel very inconvenience for all the disaster that Nusatrip has caused by cancelling the ticket that has already been purchased.
Now i am trying to find a lawyer to sue this company for all the inconvenience it has caused me and also for money not being refunded even the ticket being cancelled is not requested by me. Be very careful when you purchase anything from nusatrip.com cause even if your credit card has already been charged, the company will not issue you the ticket or even refund your money.
I am very dissatisfy with Nusatrip and will sue this company for sure unless the company sends me an apologize letter and refund my money.
