C-470 Highway is great, but paying the tolls a nightmare. I closed my account with Express Toll Service Center in October because I moved out of state. I had a $62.00 credit on my account when I closed it. On December 1 (90 days later) I received the credit and on December 13 received an email confirming my account was closed and my balance due is $0. On December 12, a statement was generated stating I owed $15.05, $10.05 for tolls on 10/1/15 AND a $5.00 late fee. When I called to get this corrected, I was told Express Toll "owned" the road and I don't have to use it if I don't like it and implied they can do what they want. When I questioned this, the "customer service" representative hung up on me. I called back, to resolve this issue and although the second operator didn t hang up on me, he also implied they can do what they want and if I am upset about it, I am being rude. I agreed to pay the $10.05 charges from October 1 (which was already paid for from my account that had $62.00 credit) but refused to pay the late fee - which was adjusted.
I am paying this $10.05 for a second time purely to get these people off my back. The statement I received a week ago (generated the day before Express Toll sent the email that my account was closed and had a $0 balance) also threatened me with a $20 collection fee because the account was Past Due .
The road is great, but the organization and people regulating it believe they own it, and treat their "customers" with total disrespect and believe they are entitled to do so. Good luck!
