My first time using the E470 toll, and I'm unable to pay by phone over the weekend because the hours on their website are wrong, along with the website itself. I tried multiple time over the last couple of days and not only is the website SUPER slow, it won't allow me to get past the screen where I enter my information. The page does not change after I enter my info, it happens even if I choose different options, whether it is to put in my statement ID, open an account, or put in my license plate info. All the pages don't go anywhere or process the info you entered. The biggest headache is I received the letter via snail mail and the bill is due today a whole $8.30, and now I will probably be charged a late fee of $5 because I'm unable to pay it by today, and have to wait until the call center is open during the week just to pay because the automated system is also worthless, it allows you to put in your info then tells you that their call center is closed and hangs up on you. This is by far the worst experience I've had with a website and business since AOL dial up was a service!
