Hello, Hearpe and all,
I think you got a really good deal on that little harp for $299! In view of that, you really should keep it and enjoy making beautiful music on it. It does look really nice in your photos, and the neck and pillar look strong. My Large Gothic 36-string has a little “lean” and “curve” in her neck and pillar now, so it is completely normal for harps to do this. Now this problem does not seem like such a big deal, and I am sorry that I advised you to send it back without considering all the facts.
Enjoy playing this little beauty!
Warmest regards,
Balfour
