Using speed pay
 

When using speed pay overthe phonedoes it give you the option to pay just the past due amount or does it have you pay the full amount.

You've got me. what are you paying anyway??

utility bill

I don't know. But I did a Google search on "speedpay reviews illinois":
https://www.google.com/webhp?sourcei...views+illinois

Maybe one of these websites will give you some idea of how it works.

Edit: I just wanted to add that whenever I have had to make a payment via touchtone phone, I have always been given the option to confirm/verify the payment at the end. I do not think any telephone payment service could automatically charge your card without having you verify the amount and confirm that you want to make the payment. Have you tried it yet? Sometimes too you can dial and hit the * key to get a human operator so you can ask a question.

Edit 2: Sorry, some of those Google websites have speedpay only in their advertisements.

Here is information from one utility company that uses speedpay:

I use "phone check" payments when I know my mailed check won't get there in time. I have only done this with our business credit card accts, I am given the option to pay the minimum due or another amount over the minimum. My Utility bills are payable in-full, I don't think they take minimum payments. Can you get a real person on the phone to ask? I would think Customer Service could.
