Network outages and signal problems in Bateleur Estate area in Nelspruit

We have been having repeated network outages and limited signal problems in our area for the last few weeks. We live in Nelspruit (Bateleur Estate). We cannot call Vodacom via 082 135 - because of the lack of signal. We cannot find another contact channel we can use to report the problem. Tobi is useless. We need Vodacom to look into the problem and resolve it.
