NO SERVICE after numerous complaints

Vodacom has now repeatedly promised to bring signal boosters to our premises (IN GAUTENG) were there is periodically LITTLE to NO signal. The technician has been here 3 times to test said signal and we were told the signal is \high in the air"- we were told that they would send someone for a signal booster - to date NOTHING has been done to rectify the issue. We are situated in the economic hub of South Africa"
