It is best not to cancel an appointment that has not been successfully scheduled and instead wait for the result. This is because each subject can only be canceled three times. Secondly, a successful cancellation reduces one cancellation opportunity, but the exam opportunity will not be reduced. Below is relevant information: Software Introduction: "Traffic Management 12123" is the official mobile client application of the Ministry of Public Security's Internet-based comprehensive traffic safety service management platform (hereinafter referred to as the Internet platform), developed and technically supported by the Traffic Management Research Institute of the Ministry of Public Security. This software serves a wide range of users, including vehicle owners and drivers nationwide. Reducing Travel Costs: The traffic management department, relying on the "Traffic Management 12123" mobile APP and the Internet-based comprehensive traffic safety service management platform, has introduced a new measure allowing online binding and self-service processing of traffic violations for non-personally owned vehicles, in addition to the existing window and self-service processing methods. As this platform can significantly reduce waiting time at traffic violation processing windows and travel costs, within just over three months, 740,000 people in Beijing have registered as new users of this system.

Last time I encountered a similar situation. After scheduling maintenance at the repair shop, I tried to cancel but failed, and the system still showed the reservation without deducting my chance. Generally, such reservation systems only count as using one chance when the cancellation is confirmed, because a failure means the reservation remains valid and the user hasn't actually given it up. However, each shop has different rules, whether through an online app or phone system. I recommend checking the reservation record directly or contacting customer service to confirm and avoid misunderstandings. It's best to develop the habit of handling things promptly to prevent issues caused by system delays. Overall, this doesn't count as a chance, but it's always wise to be careful to avoid making a wasted trip.

In my experience with car services, unsuccessful appointment cancellations are usually not counted against your usage quota. For example, in some apps we use daily, it only counts as one usage when you receive a confirmation message for cancellation. The system logic is simple - cancellation failures are often due to network or operational errors, so the appointment status remains unchanged and your quota isn't deducted. However, some people neglect to check the confirmation page, which can easily cause confusion. I recommend users take screenshots as proof each time and choose reliable platforms to reduce friction. Overall, this situation doesn't count as using up your opportunity, but it's still better to handle it promptly.

From a service perspective, an unsuccessful cancellation of an appointment is generally not counted as a used opportunity, as the appointment remains in its original state. Each system is designed differently; for example, a car repair shop's backend may automatically record successful operations, and only when a cancellation is confirmed will the user's appointment count be reduced. To avoid confusion, I recommend that users check for confirmation notifications after their operation. If no immediate feedback is received, they should try again. In any case, there's no need to worry about wasting opportunities.
