Network error/ when will the network work properly?

<p>I tried to call a friend yesterday and my calls kept on being hung up. The calls will go on and after a while they will be hung up . He will call back and the same thing will happen. I really needed to speak to my friend but the conversation never materilised. The minutes I bought were waited cause I could not make any conversations. What I would like to know is: What if I needed to make an emergency call and it was a matter of life and death? Does it mean I would have been dead cause I could not get through to actually say anything constructive because of the calls kept on being hung up and the network error that kept on prompting on the phone screen? This has been going on for months now.</p>
