How to add our website in DMOZ?

[Craig]

You have made a very big mistake submitting more than once. You agreed not to do that when you agreed you had read the terms and conditions! You only harm your chances of getting listed by resubmitting! They ban sites that do it too much!

Once you have submitted once to the one best category, there is NOTHING more you can do. DMOZ gets more submissions a day than the volunteer editors have time to process, so they will get to it one day; sometime between now and the next few years.

All you can do is get on with your life and stop worrying about it. It will get listed one day or get rejected one day. DMOZ is not a magic bullet for search engine rankings.
