I installed an air conditioner, but the electricity connection was wrong, and the electricity meter was input. Now the customer service said that the property manager said they stole electricity.

Don't worry, it's hot, it's nothing. Everyone makes mistakes. Wrong connection, because you are unprofessional or distracted, looking for the person in charge of the property in the face of customers, not the property staff, but the property manager. Explain the real situation, and then convert the electricity bill according to the air conditioning power. If the customer uses it for a few days, you can charge the electricity bill to someone else's property. Attention? The most important thing in this matter is to get customers' forgiveness and understanding first, so that customers can help you spend a little electricity on the property to solve the problem. If the customer doesn't forgive you, it will be difficult for you to deal with it! Sincere, dare to admit and face mistakes!
