Hogy kell angol nyelvvizsgán hivatalos levelet írni?

[link]

A közepén kicseréled arra, hogy:

I am writing to you because i'm not satisfied with your accomodation services at all.

Our room was dirty when we arrived: the dustbin was full of litter, the sheets were used. We couldn't use the lamp, because it was broken. We heard a constant noise from the neighbourhood, so we couldn't sleep all night.

I would be most grateful if you would reply as soon as possible so that this matter can be resolved. I trust that you will be prepared to offer reasonable compensation.

Bocs, ha hiba van benne, én sem vok profi.:D
