I read a few post in this forum and can now confirm that all these sites are fraudulent! You should NOT pay anything (even the original 4, 87$ they are SUPPOSED to charge only). I was charged close to 150$ in total on my credit card by now and I don't think I will ever be reimbursed.

You can send an email to [email protected]<[email protected]> and [email protected] to cancel your account but I have not yet got any confirmation of a refund of any sort :-(

But if someone can benefit of reading this before registering to any of these sites, it will be a good thing at least!

They are still charging me now and I am working with my back to stop this
