Vodacom Signal Booster Faulty without feedback or repairs

My cellphone signal from Vodacom is non-existent in my house on the farm at the moment. Vodacom installed a Signal Booster about 5 years ago, due to experiencing issues with cellphone signal on the farm. About 5 months ago the signal booster became faulty and since then the signal is non-existent. Since day one this was reported that the signal booster is faulty to Vodacom. Everytime we receive a progress report that the issued had been resolved. However this is false. As no one contacted us to resolve the issue. To stay on a farm with no cellphone signal is everyone’s worst nightmare, when it comes to safety (seems like Vodacom don’t care!)
