Angol panaszlevél. Nyelvvizsgán elfogadható?

3 éve dolgozok a Olasz cégnél és panaszlevelet kell írni a Amerikai főnökömnek: sokat dolgozok, néha hétvégén is, eddig nem voltam még szabadságon, nem léptettek elő, pedig ígérték, jó munka eredmény és mégsincs fizetésemelés.

Dear Sir or Madam,

I am writing to complain about the work conditions of company and my promotion.

I have been working in Italy as a Sales Manager for 3 years and I have never got recognition from you. I work from morning to evening at weekday and sometimes I work 10-11 hours a day. However I also work at weekends the last few weeks. It follows that I cannot spend enough time with my family and I have not been on holiday so far. Furthermore, I have problem with my promotion. You promised me half year ago that you would promote me, although I sent an e-mail to you related to my promotion last month but you rejected it. I think the company has been reached good results but I have not got pay rise so far.

I would be grateful if you find a common denominator related to my problems. I look forward to your early reply. I look forward to your early reply.

Yours faithfully,

XY
