POOR SIGNAL

Struggling with terrible service from Vodacom, the signal is atrocious and I live close by to one of their towers. I have tried to speak to someone within their technical division and see if something can be done or if they are planning on updating their equipment on the towers? All that happens is you get passed on from one consultant to the next. I work from home, so Vodacom is not exactly the most convenient option at the moment. If someone, the correct person can get in contact with me to assist me with poor signal, it would be great or even a miracle!!!!!
