On the 18th of May I started the trial period on the rankingcoach website.
They asked to introduce a means of payment that would be discounted €1 for the authorization and that the subscription paid would never be discounted. The same would only be deducted at the end of the trial period if it was not canceled and that they would send an email to notify.
What actually happened was that as soon as they had access to the means of payment (on the 18th of May) not only €1 was deducted but also the annual subscription value of €442.80, without having given any type of authorization.
