After reading the reviews, I found that Iwas lucky among the unlucky people who were victims to these scumbags. They got from me 250USD.
They did like many described: Share screen... when you need to click on buttons, it doesn't work, you can't click buttons.
When I said I have had enough, they refused to send me back my money, and kept harassing me via calls form all around the world (Caiman Islands, Virgin Island, Fiji, UK, Eastern Europe Countries...)
DO NOT FALL
If someone could get back their money, please share with us.
