Dear sir,

Last year I buy a refrigerator in your store on Chang An Road. We all like shape of the refrigerator. And yesterday something went wrongly. It made a noise when turning on. At first it was low but gradually it became louder and louder. To make matter worse，it even stopped working. We all felt disappointing. I am writing to ask for help. Would you please find someone to repair them? I would be at home this weekend. Please call me before you come to here. My telephone number is 66065531. Thank you very much.
