Poor signal in area

Hi have been a customer of vodacom for almost 15 years now. I have been complaining to Vodacom of the poor network signal in our area for the past 7 years now and since then nothing as been done. Each response we are working on it. others in other areas have mentioned vodacom has installed and ariel in their houses to boost signal. We live in Boskruin randburg which we all Vodacom subscibers and yet nothing has been done. Each time we need to make a call we have to dive off somewhere to get reception.I also had to get an Mtn contract to use to make calls and they recently installed a MTN cellphone tower in our area I am paying this huge bill everymonth and yet we are unable to get good signal. very poor service from Vodacom with attending to this matter and therefore I demand something be installed to boost signal.
