Form sends but no content when received

Hello,

None of my contact forms are currently correctly working on this site.
I can fill in all the form details and it seems to send a notification as if it haS sent but none come through with any content on them.

I have multiple contact forms on this site and none are working.

http://bouncerubberbands.com.au/wholesale-rubber-bands-access-request/
http://bouncerubberbands.com.au/bounce-bang/

Can anyone please help with a fix for this.

Thank you in advance.
