None of any chatting apps shows contact list
Now I realized no one can help you except yourself.
Finally i Found a way.

Navigate to Settings - &gt; Apps - &gt; All Apps
Search For contact and Contact Storage
Clear Both Apps Data

Booom You Are Done.....
Note
Clearing Contact and Contact Storage Erase Your all Contact SO make Sure you backed up your all contact online or somemwhere else. In my case I use google account.
