Thank you for the correction.
But I have a few doubts to correct. I'll start with the most stupid one. In plural form, we write
die Familie, right? Then if I were to write a reply in negative, I would say ... keine Famile. Therefore I wrote.... meine Familie.

[Except of course, I have not properly read the chapter on possessive verb form]
Ich hätte gerne Informationen
But was my use of the word 'brauche' in the context totally wrong?

Gotta memorize some of that.

But my use of the word 'Termin' was totally wrong there.
Our teacher asked us especially to take care of the 'politeness' in the opening and closing address form in the letter. They will carry some weight in our written assessment test. I will memorize those phrases too. Viele danke.
