Tata Docomo — my docomo number been deactivated all of the sudden

Address:

600119

Hi,

My tata docomo number is showing as invalid number when others are trying to call me. I am unable to make outgoing calls too. Says invalid number message when others call. Please resolve asap. This issue started suddenly by morning.

Now i am unable to raise portability too.. I have linked my docomo number to the banks and other confidential information too.

Regards,
Maha
