Part A Your TV broke down only one week after it was bought. Write a letter of complaint to the store where your TV set was bought, 1. to express what is wrong with your TV set; 2. to make your request (change for a new one, or return the broken one ... ); 3. to urge the store to give an early reply. You should write approximately 100 words. Do not sign your own name at the end of your letter. Use 'Wang Lin' instead. You do not need to write your address and the date.
