Could you correct my formal complaint?

26th February
Plaza Mayor 1
Valladolid

Dear Mayor,
First of all, I wish to complain about the noise made and the mess left in my neighbourhood every night by the local refuse collectors. I think that the timetable is not the most appropiate because the refuse collectors wake up many of the local residents. It would be better if they did their work during the morning or the afternoon.
Having said that I know that it is very difficult to fit everything in the timetable but in my opinion this problem is due to the fact that too few people are employed for the work which has to be done.. The solution for this problem would be to employ more workers so that they could work during normal working hours and therefore would not disturb people at nights.
However I write this letter as the spokesperson for my block and not as an individual. It is the complaint of many in this neighbourhood and we would be thankful if you could do something about it.
Thank you in anticipation.

Yours sincerely,
Gonzalo Sánchez Barbero
