Sends 5 emails and adds 5 records everytime

Hi Kevin,

Trying your use your testimonial plugin having strange issue when I click Submit button it sends the same emails 5 time to admin and user. It also adds 5 records for every email sent. Very strange behavior. Tried disabling other contact forms etc with no luck. Makes your plugin useless in my case.
