Gadgetsworld.com taking money from my acc in USD via gardenshop

Please be careful as you get an email from marketing@gardenshop.co.za saying you have won and just complete a survey. The moment you enter your banking details you get hacked and whacked by Gadgetsworld.com. They took and estimated 20 USD from my bank account. I was in this screen which I could not get out of, and could only get out once I restarted the PC. I used a virtual card which I could then stop with my bank. Gadgetsworld now refuse to refund me, I did not want to sign up for any subscription with them, this is international bank fraud. Please advise all your family, friends, parents, children that they must not accept any email or such from gardenshop or gadgetsworld.
