I am the latest victim of these scammers. This morning I searched using SkyScanner.net and found a suitable route on TRIP.AE. After booking the ticket from DOHA to Vancouver for USD 1754.86, I had to cancel due to personal reasons within 1 hour. Soon after canceling, I got an email from TRIP.AE stating they had initiated a refund of USD 1666.36, while at the same time, the website tried to deduct my credit card for USD 1666.36

After filing the Dispute Form with my Bank with all the evidence, I got an SMS from the Bank stating the refund amount had been initiated successfully and should be in my account in 3 working days. I am not sure if it's due to me logging the dispute form or if it was by the Merchant.
