SIGNAL PROBLEM STILL NOT SORTED

I logged a call with them on the 03rd of July 2015, Reference number: A1-X6PQP1ED, as we have no signal in the area where we live, needless to say we have been complaining for years, we had a booster which was installed, and they came out and repaired it, it worked for about 2 weeks and then no signal.... I have been in contact with a gentleman by the name of Bo, who has on numerous occasions kept me updated. A lady came out, tested the signal and agreed that it was terrible and she would arrange for them to come and sort it. The last time Bo phoned me he said that the technical team had been out and it is sorted, which is not true, nobody has been out to sort this problem and we are now going into October!!!!!! He said he would follow up and get back to me. I called the call center again and asked to speak to Bo only to be told that he will phone me back, this was about 3 weeks ago..... I am still waiting. We are the emergency contact for our parents, but they can never get hold of us, we cannot phone or receive calls as there is no signal. It seems as though Vodacom does not give a damn about their clients.
