I have noticed on many developer facing problem with no CAPTCHA code display problem with “wordpress Contact form plugin”.
Its really easy to install and use, just like pepsi can open and drink, 
but make sure these steps:
- Make sure GD and FreeType libraries are installed on your server.
- Make sure wp-contents/uploads/wpcf7_captcha folder exists and is writable.
most of time i have seen developer not care about “wp-contents/uploads/wpcf7_captcha” folder exists or not, be smart developer and must check it, if there no folder, create “wpcf7_captcha” and give write permission to it.
and check it will work fine,
