I'm not in the U. S. but when I tried to cancel my Bitdefender subscription last week (substituted Windows with Linux) - surprise: there isn't a Cancel Option anywhere on my account pages. No chatbot, no e-mail address, no phone number. I opened a ticket with them and the answer I got was: cancel via snail mail with the service provider. I live in a 11th century 200 inhabitants village and the next post office is 10 km away.
These practises have got to stop. We've got to regulate this away, it's borderline fraud.
