Hopefully the company can help you with it. Good customer service would be to send you replacements free.
I would hope for a free one. Sounds like occasionally they have a defective one since googling it resulted in basically nothing so I'm guessing it must not be a widespread problem.

Hopefully one of those email addresses will result in something helpful.
