Reliance Communications — reliance network

It is really very frustrating - there is no network inside my house. No one can hear what i am saying as the reliance network is not picking up the signal. It was relatively better 6 months ago. Now, it is extremely bad. I am planning to switch to another service provider though i have been with reliance from day 1. Not only do i miss some important calls but also people are worried when my phone always indicates a "switched off" mode. I tried making a complaint just now over phone, but i get a recorded message says that there is some technical issues and hence they cannot attend to my call.
