Number of Character slots?

Hey guys! I played MS about 5 years ago and have never bought any additional character slots. My old account has 9 character slots. I recently started playing again and decided to start from scratch by creating a new account and trying out the new classes, Evans and such. The account that I most recently created only has 5 character slots. Is that right or should I send a ticket into nexon?

Thanks for any help you can provide!
