Answer:
Make a normal letter starting off with your address, date, name, company you are writing the complaint to, and the location of that company. then start off by saying dear "person". You also want to say "Re: Steam Iron" because you are replying about that.
make a paragraph or a few paragraphs about what is wrong with what you ordered.
end your letter by saying something like "Sincerely (Customer)"
