We apologize for the confusion. It takes up to two weeks for bills to be processed. If you received a billing notice, that means that at the time it was sent, payment had not yet been posted to your account.
If you'd like to confirm that payment has been received, please call our Customer Service Center at 214-745-8383 during normal business hours. Representatives are available Monday-Friday 7:00 a.m. - 5:00 p.m. and Saturday-Sunday 7:00 a.m. - 11:00 a.m.
