Delhi Traffic Police — Not returned my suspended licence after completion of 3 month

Address:

New Delhi, Delhi, 110044

Why they are suspending the licence if they are not aware that the licence holder would get his licence in future or not???
I had been to nehru place at traffic police office as they told me to come after completion of 3 month, they told me that they have forwarded my licence to my authority then i had been to my authority they are saying that they are not aware about my licence and suggested to go back at nehru place office...
How will i get my licence... Rohit kumar_[protected].
