Sir,we bought a refrigerator in your store last month.
But recently,as soon as we turned on it ,it made noises.
At first the noise is low,but gradually it became higher and higher,and sometimes even the refrigerator stopped working.
We felt so disappointed with it.
I'm writing to ask you to send some one to mend it.
This weekend I will be at home.Please call me before coming,and my telephone number is 86606553.
