Translation of Klopapier

The billing of additional working hours is not justified, since it was our request to download the software and wait for the new version. They have admitted the error of the translation.
Thanks a lot. My wife, daughter and I came back with a flu from the Swiss mountains, but now we are getting better. How are you? 'Vos' is only used in antique Spanish as 'usted', in the singular form of course.
Thanks for the corrections and for accepting my friends request. You are completely right: Spanish grammar is simpler than German grammar. I was just looking for a job where both languages are required.
