No signal for days

We have been struggling in our area since Monday without any signal. We can't make any phone calls nor receive any calls or messages. I have called Vodacom several time to report it and all they say is we must wait 24 hours for them to call me but how can they call me when I don't have any Vodacom signal. Why don't they just send someone out to the area and see what the problem is and fix it. It has been 14 weeks that the signal comes and goes but now it is off since Monday. How must we pay our contracts at the end of the month if we do not have signal most of the time? But if you dont pay then you will hear from them very fast. This is so frustrating.
