The checkout system allowed me to pay for a course without registration. Then I received an email confirmation saying I had to login to download my course even though I hadn't registered.
Having registered and logged in, no course was available to download and my course was still in my shop cart indicating no purchase had taken place, even though my card had been charged.
I complained via the customer services area and got a sarcastic response and they then emailed a PDF with a link to download the course.
Upon download I discovered it was no the course I ordered, i. E. a different language.
This is a professional looking site but appears to be a scam.
