Dear /Madam
I am writing to complain about a news article printed in yesterday´s newspaper.
I believe that your article did not represent both sides of the argument. I have been reading your newspaper for many years and one of the things that I value is your reporting which is normally impartial. However, on this occasion I believe that the facts were not clearly stated.
I would be very interested in knowing your comments regarding the above complaint.
I look forward to hearing from you.
Yours faithfully
Tamara Rodriguez
