Bad reception in Sunninghill Johannesburg

I have been living in Barbeque Downs, Johannesburg for two years now and in the last year I struggled permanently with reception in the area. My phone (iphone 5) is permanently on edge with brief moments of 4G. There is a lot of development in the area and I believe more towers and RF antennas are needed with the influx of sudden houses and flats. <br> <br> My 3G ****le is also Vodacom and I can never get reception in my house and have to go outside with my laptop in order to get reception.<br> <br> I have been with Vodacom since the start of cellphones around 15 years and if it does not change I will have to change my service provider.
