Cancelling subscription

I have had a stroke, and don't know the email address nor the key I used when I bought CCleaner Pro. The subscription fee appeared on my bank statement. How do I cancel my subscription without that info?

I'll pass this up to the Piriform team so they see it, and contact you.

Hi Nancy, we're sorry to hear about this. You can drop our team an email on support@ccleaner.com and they can look into this for you. Hope this helps ?.
