Tata Docomo — deactivation of my docomo sim

Hi
My docomo number [protected] was switched off past few months. But i was using my whatsapp from that number. Today when i turned it on, i was showing me "emergency calls only." and when i am calling on that number from some other number it's saying that the number is incorrect. Please resolve this issue asap. As that number is attached to all my bank accounts and many other important contacts. Reach out to me at [protected]. I am trying to contact you people via customer care but not getting any response.

It's urgent. Please take this complaint in your priority list.

Thanks
