Empty promised and lack of service

In August 2014 I requested assistance with the terrible signal we are experiencing. We will have NO access (phone calls or internet) for days and if we do have signal it is EDGE, but only for a few minutes and the signal is too weak to access my internet. If however I want to use my internet, I have to sit outside in the garden...because that is the only place I have signal. So what do I do in winter?????<br> <br> Months later (March 2015) I received an e-mail to rate their service as the problem was fixed...sorry to say, but we have the same problem and nothing has been solved!<br> <br> We are not the only household in this area struggling with signal, many people in the area are Vodacom clients and we are all struggling with the same issue. <br> <br> I need to know if I must change my network or if I must bill Vodacom for thermal jackets so that I can at least use my phone and internet through the winter.
