Idea Cellular — voice drop and network not available

This is the third time i am complaining on the same issue.
Worst service from last one week.
We are not able to talk continuously with anyone. After few minutes or seconds, the voice drops and cannot here the other person speak.
I want it to get resolved as soon as possible. The basic call is not working now in idea network. Very unhappy with the service.
I do not want to raise the same complaint once again. Please resolve the issue and let me know.
Please do the needful.
