Homework. A letter of complain To whom it may concern, I am writing to express my strong dissatisfaction with the service I receive during my flight in your airline. I recently return from my family holidays in New Zeland on flight SP45628 which arrived at Madrid airp. on 10/25/17. First of all, I paid 50€ extra for each (4 people), for the service "boarding first" to avoid make queus and select our seats. Nonetheless, my family boarded the last for unknow circumstances, and the seats we booked were occupied by other passengers forcing my family to look for empty seats and travelling separated. The straw that broke the camel's back was that because there were not available seats, my tot traveled on the top of my chest, being both impossible, sleeping or adopted a comfortable posture to rest. To make matters worse, the flight attendant were not only unprofessional, but also rude, being unelpful to solve the situation. It seems only fair that you should offer a full refund of the "boarding first" service and an extra compensation for the inconvenients I suffered. It would be advisable to take the necessary steps to ensure that such incidents do not happen again. I expect to receive a prompt rely to this letter. Yours faithfully,
