The firt thing you should do is contact the outlet you bought it from: i.e. handango or pocketgear.
That is the quickest and easiest (if you were prudent enough to keep your email address and the cc you bought it with).
If that doesnt work, then you contact support@pdmamill.com... then wait three days.
If you still have no reply, or no clue, then email me at jaybot7@runbox.com and i'll take care of it.
