I have previously considered to study the UOL computer science degree course that UOL had liaise with Coursera.Just recently I tried to test out Coursera Free trial. I have had cancelled the free trial, and also my own credit card as I had previously bad experience with other websites in their handling with my card information. Coursera started billing me just 3 days ago I was astonished! I have did what I can to remove my card number and the subscription, and yet, this stinking thing happened. There are many bad website and system on the internet but Coursera is the worst I have ever experienced. Never am I gonna even study on Coursera again and I bid everyone to think twice if they were ever contemplating on using Coursera. They refused to even give me a refund! I hate giving negative reviews, but this is just unacceptable.Edit, they refunded after much perusal. But that was still a rollercoaster ride.
