MoviePass is enrolling some subscribers who had previously canceled the service into its new plan, which is expected to be implemented this week.

Some subscribers received an email that they had "confirmed" their new MoviePass plan, even after canceling, with a note at the bottom of the email that said their "opt-in to the new plan will take priority" over the cancellation.

Many of these users are complaining that they can't re-cancel MoviePass, and receive an error message when they attempt to do so.

MoviePass is rolling out a new plan this week, and wants its users to experience it — so much so that it's re-enrolling some users who had previously canceled the service.

MoviePass users have taken to Twitter to voice their displeasure with the service, and several have emailed Business Insider about their frustrations. MoviePass is expected to implement a new plan by Wednesday in which users will once again be able to see any movie they want, but will be limited to three movies a month for $9.95.

But there are MoviePass subscribers who had already jumped ship, and some who had canceled the service recently have found themselves re-enrolled into this new plan, they said. Several of these users received an email from MoviePass that they were signed back up, with a note at the bottom that reads, "Please note: if you had previously requested cancellation prior to opting-in, your opt-in to the new plan will take priority and your account will not be canceled."

Below is an example of the email, provided to Business Insider by a MoviePass subscriber who had canceled the service:

One MoviePass user told Business Insider, "I actually canceled the other day (or so I thought), but then I got an email from MoviePass saying they had taken the liberty of signing me up again."

Another said, "Cancelled my MoviePass two weeks ago. Today I received an email from MoviePass updating my membership to 9.99 [note: it's $9.95] for 3 movies per month. Went into my account to find that no, my account is not cancelled. So I went through the steps to cancel AGAIN, and am receiving an error message."

Not only is MoviePass enrolling users who had cancelled into the new plan, but it's making it difficult to cancel again, several subscribers said. Many on Twitter have complained that they receive an error message when they attempt to re-cancel.

MoviePass did not immediately return a request for comment.
