I was tricked into a subscription by them offering to tell me what my ethnic make-up is - now wonder if what they told me is correct. I wrote to their support email address, saying that I want to cancel my subscription and gave them 24 hours to respond - no response. Even before the trial had ended, they applied to my bank for payment. Fortunately my bank blocked them.
Since then, they have tried again to get payment, and sent me an email to tell me to get things sorted, to which I have once more replied that I do not want this subscription.
Unless you want health advice, I would avoid them like the plague, as their trial is not a trial which you can easily end. Their cancellation policy is a SCAM
