No Signal- No solution/feedback from Vodacom

I recently moved to Bromhof, Randburg Gauteng, my husband and I (Both vodacom customers for years) cannot access the internet or make calls in our home or even in our driveway from our smartphones or using our Vodacom ****le. There is no Vodacom signal. My friends' MTN phones and 3G cards work perfectly from our house! I logged a call on 1 Dec 2015 to get a signal booster for our home to resolve this and was told that a technician would contact me within 24-48hrs to come to our house to assess regarding a signal booster. I had follow up after 2days of hearing nothing. Only to be told they're working on it and would contact me. It is now 9 Dec and no one has contacted. I had to follow up again to day (on hold for a very long time!) and was not given any solution or timeline on when a technician will resolve. It is Dec and I am concerned that if this is not attended to this week, I will spend the whole Dec into Jan without signal. I am seriously considering getting an MTN contract coz I cannot operate my personal or business life from my home. All I want is feedback, a solution and clear timelines! I can't be expected to keep following up when I am told that someone will call me!
