Tata Docomo — if any one is calling it says "number invalid or number galat hai"

I am fed up with this, no one is able to call me as it says "invalid number". I am able to call people but unable to get calls. This is happening with me from last 2 to 3 months. I have complained 2-3 times but no one is giving a proper response. I have been told to call on number #35*1234# and it, it said call bearing has been disabled. But still my issue persists. No one is able to call me, parents, friends, relatives even important calls from my working place. Its rreally frustating, not expecting this from tata docomo. Please look into this asp.

My number is - [protected]
