Hello i would like to cancel my subscription for ccleaner for windows. I cannot do it through my computer as it is no longer functional and there is no way to do so through your website. I can send you my product key if necessary.
Thank you
You will need to contact support to cancel your subscription, for security reasons it's not something that can be done on an open forum.
You can email them at support@ccleaner.com
It's best if you can email them from the email that you used when purchasing CCleaner, if you can't do that then giving them that email will allow them to track down your account more quickly.
Alternatively as your computer is no longer functional you should be able to download CCleaner Free on another computer and use your product key to upgrade it to Pro.
That should then let you use the Manage Subscription Button in CCleaner itself.
Thanks
