Dear Manager, I venture to write to complain about the quality of the digital camera I bought last Friday at your store. During the five days the camera has been in my possession, problems have emerged one after another. For one thing, the screen is always black, making the camera no different from a traditional one. For another, the battery is distressing as it supports the camera's operation for only two hours. Therefore, I wish to exchange it for another camera or declare a refund. I will appreciate it if my problem receives due attention. Yours, Li Ming
