Dear Sir or Madam,

I am writing this letter to express my disappointment with a recent purchase on your online store, order number #7298883. I ordered a set of soccer equipments that were advertised on your site as a package including 3 pairs of socks and a pair of soccer boots. However, on their arrival I found out that there were only 2 pairs of socks. In addition, there were scratches on the boots that suggest that they had been used before and returned to your store.
