Problems with the Toots Mellow Tone

[rmarco@xxxxxxxxxxxxxxxx]

   I've bougth a Toots Mellow Tone Hohner Harmonica yerterday. When I blow
 on the hole 2 (MI) it sounds a awful metallic jingle. And when I play the
 last hole 12 aspired (SI) it sounds much worse than my old Mellow Tone.
  Is there a easy solution for this problems? Should I back to the shop and
 ask a solution (change it for other new harmonica)?
