Vodacom Red VIP - technical support

Vodacom Red VIP - hailed as a "Premium Service" - yeah right.... I am dealing with a technical Cellphone reception issue in my area. Vodacom has installed a direct aerial on my house and a signal booster inside the house, which worked very well until last Feb this year. I have lodged a service call on 26 Feb to inspect and investigate the issue - which will require that technician comes to my house and checks the items installed. Reference number given, all good. No visit, no change. I call some time later to follow up as there is still no change, only to be told that the reference number closed because the issue was "solved". Far from it though - blatant lie. I then re-lodge a service call for the same issue. I am promised that it has been "escalated" and it will be physically attended to within 24 to 48 hours. Now, several days and several calls later still nothing has happened other than I have been told that the issue has been "resolved". Pathetic Service - stay away from this company!!!!
