a formal letter

Dear Sir / Madam,

I am writing to inquire about the malfunction of the heating system in room number 72, Four Seasons Hotel. London, England, Unfortunately I had three miserable days from March 08 - 10, 2014.

When I arrived in London, there was an unexpected snowstorm. I understand that it doesn't snow in March usually; however, when I got to my room, I realized that the heating system was not working. After complaining, they sent a technician who informed me that he needs to install a new heating system. I asked to change the room, but they said all of the hotel's rooms were booked. Unfortunately,  I was going to work and came back to discover each time that the problem was not fixed. Therefore, I spent three horrible nights with no heating. Moreover, I ha to wear my coat in my bed - also my socks - and I ended up with a bad cold from an unheated room.

I won't recommend this hotel to anyone; the service was extremely terrible and no one would expect an uncomfortable room when paying 200 pounds. I am asking for compensation for this inconvenience and a full refund. Otherwise, I will take my complaint to the highest authority.

I look forward to hearing from you soon.

Yours Faithfully,
Ahmed - Well written Ahmed!
