I bought BitDefender totalsecurity more than a year ago. And there is a tiny checkbox to enable Auto-Renewal that I overlooked. Now they are gonna charge me every year and there is no way to cancel it!
Sent 3 request e-mails, talked to their customer support chat. No use. They said they will forward the request to the relevant department! WTF. There is no "Unsubscribe" anywhere. You have to fill-up a form and submit it!
