Problem with bots

Hello (First sorry for my english...) I have problem with bots.

I have a form that has a field validated and required, for example, e-mail box additionally form is protected by captcha. Despite these security bots send me messages and fields, for example, email is sent as empty as is normally impossible. How can I solve this problem?
URL ancacars.pl form is in place on the top of the page the 'check availability'.
Regards

Hi malkovic,

The form looks OK from the front-end. Do you have the Check Captcha action before the Email action?

Please see this FAQ

Hi GreyHead,

Check operation Captcha before sending e-mail?
I attach a screenshot of what it looks at backend.

Best Regards.
