So here's a question for you that you may want to try and send to me.

''Your company employs an office cleaning service to clean its offices every evening.
Your company is dissatisfied with the service and you have been asked to write a letter to the office cleaning service''.

Write your letter to the office cleaning service
*explaining why you are writing
*describing ways in which the cleaning service is unsatisfactory
*saying what effect this has on clients visiting the office
*outlining what action you intend to take if the service does not improve

I'll give you a model answer and some tips in future bulletins...
