The battery car management staff in the park are very unprofessional. Of course, they don't know if it is intentional. They don't know how to calculate the cost, and they don't know where to stop. If they stop, they will be fined, let alone informed in advance. Later, they promised to refund the money and said that it was not counted. Anyway, I haven' Suggestion: clear the rules and charges in the eye-catching place, cancel the on-site manual (feeling that they are more like fooling, no service attitude at all), scan the code to use the car, so that people feel better!
