If a no-star review was available, I'd give it. The way these people do business is criminal. I paid a bill online, and thought that was that. Then, I continued to get bills for the one ""toll violation"" and I thought it was just a mistake on their part, that they had sent the bills before the payment had processed or something. So, I tried to log on using the Reference Number (they use one number for one violation), and it said I had no existing bills for that number. So, I went about my business thinking the bills were a mistake, since I'd paid. I continued to receive them sporadically (one month, nothing; the next month 3 bills). Finally, I called. The young lady on the phone informed me that originally, I had only paid ""Part of my bill"". To which I responded, ""I paid what the online account, and the paper bill said was due."" And she said, ""Yes, our system hadn't updated, and you owed more."" And I said, ""I tried to log on again, and it told me that I had no charges on that Reference Number."" And she said, ""Yes. Our system only allows you to make one payment online or over the phone."" Long story short, because THEIR system had not updated and because THEIR system won't let you see your bill a second time, I ended up racking up more than $60 in late charges and no matter how many calls I made, or strongly-worded letters I wrote, they refused to knock off the late charges because of THEIR F-ING SYSTEM MISTAKE!!! I am writing more letters to the Cen. Tex. Regional Mobility Authority and TXDOT to thouroughly express my frustration. I made sure to take down the date and time of my phone call, and the name of the customer service representative who insisted that I had no other charges for that license plate, just in case. From here on out, my husband and I are avoiding the 183 tollway at all costs so that we never have to deal with these crooks again.
