We signed up with Perfectmind and have cancelled our services back in July and are still having charges come out of our account through their 3rd party - Paysafe. When I called them in December they informed me that they are still able to take money out of my account for up to 12 months. How is this even legal?! I highly recommend NOT signing up with them. This was not the first time I have had issues with them.
