Who to Contact for ETC Overcharging?
2 Answers
In case of duplicate ETC charges, users can print the detailed statement at the corresponding bank branch and call the expressway customer service to provide feedback. After verification by staff, the refund will be processed according to the refund procedure. Here is additional information: 1. ETC System: The ETC system performs wireless communication and information exchange between the onboard unit installed in the vehicle and the antenna installed at the toll station lane. It mainly consists of an automatic vehicle identification system, a central management system, and other auxiliary facilities. The vehicle identification information is stored in the onboard OBU, which is usually installed on the front windshield of the vehicle. The RSU is installed beside the toll station, and the loop sensor is installed underground in the lane. 2. Two-Way Communication and Data Exchange: When a vehicle passes through the toll station, the loop sensor detects the vehicle, the RSU sends an inquiry signal, and the OBU responds, enabling two-way communication and data exchange. The central management system obtains the vehicle identification information and controls the management system to perform different actions based on different situations, such as the computer toll management system deducting the applicable toll from the vehicle’s prepayment account or sending instructions to other auxiliary facilities.
I've been driving for over a decade, and ETC overcharging is quite common with several possible causes. For instance, the system might deduct fees repeatedly, or the device's film might not be properly attached, affecting the signal. Sometimes, toll stations' recognition errors can also lead to overcharging. Whenever I spot anomalies on my bill, I immediately check the transaction records through the ETC official app and take screenshots as evidence. Then, I call customer service to file a complaint, specifying the exact deduction time and road section. Usually, they verify and refund within a few days. I recommend regularly checking the bank statements linked to your ETC to prevent minor issues from escalating. If you're in a hurry, you can visit a bank counter or the traffic management bureau for on-site resolution. Though time-consuming, this method is safe and reliable.
