Dear sir,
Last year I buy a refrigerator in your store on Chang An road. We all like shape of the refrigerator. And recently I find something is wrong with it. It begins to make noise when it turned on. At first it is low but gradually it become louder and louder. To make the matter worse, it even stops working sometimes. We all feel disappointing. I am writing you to ask for help. Would you please send a people to repair it? I will at home this weekend. Please call me before you come to here. My telephone number is 6606.5531. Thanks you very much.
