Vodafone Idea Limited — data

Address:

Narayan Medical College and Hospital, Intern Hostel, Room no-145, Jamuhar, Rohtas, Bihar, 821115

I am using Idea since 1 year but I can't use it regularly because there is one to two signal bar. I can't make calls neither on 4G or 2G. Even if call gets connected then other party can't hear my voice . Even if I switch to 2G network in which i get full network bar the call quality is same. I can't use data service as internet does not work. I have complained them many times but company didn't solve my problem. They always lied that my problem is solved. Please help me with this
