this complain is against tata docomo. i have been using the number for long time. Suddenly, since last two days (from 23rd Oct,2018) I see no service. i tried to put complain on tata docomo portal,there i am able to see it is not a valid docomo number. this is really disappointing.
How can you deactivate a number without any prior notification. it is a very important number for me.
please check ASAP
