I recently signed up to the free 7 day trial. Whilst I did enjoy listening to the sleep stories and found them very effective, I also subscribe to audible and can get something similar. I decided to cancel,but was a day late and was charged £39.99. They had emailed me to warn me that the free trial was about to end, but I hadn't seen it. I immediately emailed the customer services team and received a refund the next day. I have to admit I wasn't expecting the refund after reading the negative reviews, but in my experience I couldn't fault them!
