This is the 5th complaint I have placed here about Vodacom regarding the complete disappearance of signal on Red Hill, Cape Town in November 2015. After my 4th complaint, they eventualy sent someone round to check this. I was told I would hear back from them with their findings on the 14th of January. I have heard nothing so far. I have no other way of contacting them and actually speaking to someone who can help me except by posting something here. So thank you for this portal to them. My reference number is A2-1I7I-GLDUF.
