[Resolved]  Tata Docomo — "dive in now" pop up not disable

Address:

Bangalore, Karnataka, 560076

Hi, I am getting a DOCOMOs Flash alert on my mobile (MOTO G 3), like "DIVE IN NOW", with OK and CANCEL button. No matter what button is pressed it again pops up. If I click outside the flash alert, within 1 minute it will pop again. I am not able to perform any other task when this happens. It last for at least half an hour. I called Customer Care and they told me like its a setting done from my mobile, like Go to Settings > Message > Disable Service Msg/ Flash/ anything related. But no such options were available, when I told this they said they are not responsible and can't do anything. Is there any solution for this other than number porting?
