I had qualified for VITEEE with 47000 rank . but somehow misses my counceling . what i must do now ..?

You can participate in other rounds of counselling you can get CSE in vit bhopal campus and ECE in vit Chennai campus.
There are also direct admission in vit by which you can get admission in any branch but  you need to pay extra for it.
If you have missed the counselling then you can contact them on their helpline numbers, counselling is going on niw so you can participate in other rounds.But you need to visit the campus for your counselling to get admission.
You can also contact the agencies which provide direct admission in vit.
I hope that you will get admission in yiur preffered College.
Good luck for your admissions.
