good note i would like to cancel and no longer be charged to my credit card.
How should I proceed?
This is a user forum, we can't really help with that. I believe if you email support at support@ccleaner.com they'll be able to walk you through canceling automatic reregistration.
You can also find some instructions on cancelling your subscription here: https://support.piriform.com/hc/en-us/articles/360020674812 - however, as Nergal said, please feel free to get in contact with our support team either via the Contact Us button in that article or by emailing the address he provided directly, and we'll be happy to look into the matter further!
