Pathetic no signal for days on end...

I am sick and tired of MTN not working where I stay. In the past 3 months we have had no signal numerous times. About 2 years ago I had a fight with MTN regarding weak signal after we had very good MTN signal, they then installed a signal booster at our home now 2 years later. No signal for days on end even with the signal booster. I jave reported it a few times but it is difficult of you have absolutely no signal and have to drive to a place with signal to report it. Really pathetic MTN we stay on a remote farm location with no signal and I can't even go to Vodacom because they have no coverage in my area. It is a huge security risk, thanks to your pathetic service.
