Dialogue en anglais correction svp

Bonjour a tous .
Voila j'ai un dialogue à écrire en anglais et j'aimerais savoir si vous pouviez m'aider à corriger mes fautes svp

It was a cold and rainy afternoon, Mr N was sitting at his desk working on his files in his office. It was 3p.m when the phone rang
-Hello, N's Angency, what is it?
-My name is M. I don't hink you remember me.
-No
-Welle let me remind you about me ... I was an aborigenes and you brought me in the "MRNS"...
-Ah...the "MRNS"...That remind me bad memories...
-So...Do you remember me ?
-Certainly not , I've seen so many Aborigenes children there,and for me they were insignifiant , unless if ther were quite white for me ...
-Anyway... To be honnest , I just call you for know why do you lead up us to that school . BEcause now, government send me back to Australia and I live in dreadful condition... I have lost everything in your rapt and gain nothing so ... Why ?
-Well... You see I made an error... I thought that half-cast could become white like us , I mean ... Human as us. But ... I was wrong ...
With time I have become aware of your culture and way of life. I saw that Aborigenes were human as us ... MAybe more than us , when I see what we made against Aborigines ... We ruins so many aborigenes life... I really regret what I'vs done , i don't ask you to pardon me ... I know I'vs done horrible thing ... I'm really sorry ...
-I... I see ... At least I know why I was rapted long ago... Even if you did bad thing , I pardon you. But now try to help Aborgenes ...
-All right , I will did it
- thank you farewell
