when i raised issue using email they asking me proof. i attached the screenshots but they again asking for proof, now how to give it? i just don't know! speed is mostly in kb and few times as worst as 20kb.
When I went to JIO store they just said i live in that area and it works well there. now what to ask those fellow! i'm really upset by the service. need a solution soon
