The final bill is not prorated. You are advised to cancel your service during the last week of your monthly cycle.
I'm bummed hearing you're considering leaving krismeister. I do hope we've done everything we can so you can stick with us. As mentioned above, this isn't prorated so we encourage that you wait until the end of your cycle before canceling.
If you do have any further questionsl, you'll want to Contact Us and speak with our Customer Care team. They can look at your account and go over any other specifics about the bill.
