I don't think you will get back that money, perhaps it's a lesson learned, and you have to be a bit more careful next time round. Researching around would have help avoid you from getting scammed.

On Trustpilot, ignore the fake 5-star reviews, and you will realize that there are a lot of people who have been scammed.
