Your DM is also out of line. One of the few things a DM cannot under any circumstances do is tell a player how to play their character. The DM has an entire world they get to play with, they don't need to be messing with your one person as well. At most, they can tell you that they don't think your behavior matches your stated alignment.
Keltest has the right of it.

I do disagree slightly with them, in that if you write Neutral Good on your sheet, you should attempt to play your character in a Good fashion. That being said, if you don't, that doesn't mean you're playing your character wrong. That just means that you wrote the wrong alignment on your sheet, or that your character has changed from Neutral Good to something else.
