Hello, MustangZ66, welcome to the forums!
You can set up a Promise to Pay without giving us any of your card information. This is just telling us that you're going to pay on a certain day to ensure your services don't get interrupted. If you'd like to take advantage of this option, feel free to send over a PM with your first and last name.
