Your Netflix plan will never change unless you’re notified about it by the Netflix team. If something changed in your subscription, such as its price, check the email address associated with your account. If there are any changes in pricing, Netflix will notify you. You should also see a message on your display as soon as you sign in. You can expect to receive this message a month before there’s an increase in the price. If this happens, according to Netflix, it’s because they’ve added more shows and improved the quality of their service. You will be able to cancel your subscription at any time if you're unhappy with the change.
