Tata Docomo — call diverted to docomo divert

Sir/ ma’am,
My number ([protected]) recieves no signal, and my calls keep getting diverted to an unknown number i have tried the code #002# but nothing is happening my network is still lost and my calls are still diverting. I am having a lot of troubling contacting people in any situation and its been a while now that things have not improved, earlier ut was working perfectly fine but now its causing utmost difficulty to reach anyone. Please help me, or else i will have to port my number.
Thank you
