I've taken a PHP programming course at Coursera. I wasn't able to finish the course because I was disconnected from the Rhyme virtual desktop environment they provide right in the middle of the course. Now I am being redirected to the quiz while I wasn't even able to finish the course. There is no way of contacting them so I just gave up on requesting a refund from them. In my account they marked my course "non-refundable". But then on their website they claim that they refund within two weeks. I purcahsed my course one week ago. They don't mention a single word why they mark some courses non-refundable. Coursera feels like a very strange company. It feels more like a total rip-off than a platform dedicated to education. It was a total waste of my time!!! Never ever again Coursera....
