The relationship between the customer and the company is a kind of contract, which is changed without the customer's signature, indicating that there are serious problems in the company system.
If the staff of the business hall "forges" the business form and imitates the customer's handwriting for signature confirmation, then in a sense, it has violated the customer's name right. If the business hall staff in the whole province and even the whole country are so free to operate, it will be a mess.
Business hall staff who violate work discipline, professional ethics and illegal operation should be fired immediately if they can't give a legal and reasonable explanation.
Compensate customers for all losses, restore the original packaging, and apologize. To sum up, customers feel insecure when they go to the business hall to handle business.
