To avoid service disconnection, it is very important to take action on past due bills immediately.
If you receive a disconnection notice, please call our Customer Service Center at 1-800-ALLIANT (1-800-255-4268) right away to discuss a payment plan and to learn about our payment options.
Making a same-day payment
You can pay a past due bill with one of our same-day electronic payment options:
If you choose one of these options, please notify us that a payment was made using Speedpay or Western Union; we'll verify your payment with the vendor and note it on your account.
Please note: These third-party providers charge a transaction fee for their services.
