Is it tricky for people who claim to be high-speed management stations to promote etc on the traffic control office?

According to our life experience, all preferential activities have a deadline, and ETC is no exception, so the second thing we need to find out is how long the discount is valid. For example, the ETC charges advertised by some banks are 7-8 fold, which makes many car owners feel excited, but after handling, it is found that only the first brush or the first three brushes will be discounted. Many car owners who know the truth have also shouted grievances, but it is too late. After all, they have already dealt with it, so they have to make do with it. The third point is closely related to our own interests, that is, whether ETC needs to re-open an account, because many car owners have indicated that they need to re-open an account for ETC, which leads to some hidden charging problems in the new card opening. At the beginning of the card, the bank staff will not take the initiative to explain it to you, but must take the initiative to ask. The last point is about the maintenance, cancellation and after-sales of ETC, which is also a key issue to help us use ETC better. Therefore, before dealing with ETC, we need to ask the following two questions clearly: First, who will bear the maintenance cost after ETC equipment fails? The second is how to cancel the ETC installed in the transfer vehicle.
