Can confirm, this happened to me a few years ago. Thankfully I realized it minutes after it renewed itself and managed to get a refund, but the customer service was adamant that I did not turn off auto-renew. I did. I specifically double-checked a week before my plan was supposed to expire–I always have subscription expiration dates on my calendar bc of shit like this. Deleted my account as soon as I got my money back. Fuck NordVPN.
