Automatic renewal & refund

Dear Parallels Support Team,
I am writing to formally dispute an unauthorized charge for the auto-renewal of my Parallels Desktop for Mac Business Edition subscription.
(Cleverbridge Reference: 518500260)
Issue Summary:

• I did NOT authorize this automatic renewal
• I did NOT receive any advance notification or reminder about the upcoming renewal
• The charge was processed without my consent

I checked my email thoroughly, including spam/junk folders, and there was no advance notice of this renewal. Without proper notification, I had no opportunity to cancel before being charged.
Request:
I am requesting an immediate full refund of this charge
I expect better customer service from Parallels and trust this can be resolved promptly.
I await your urgent response(email:kjseo@saluscare.co.kr).
