**** signal and poor support and knowledge structure

For the past 3 weeks I have been having a problem with data signal in my area. I have tried several times to call vodacom but even that fails as their calls keep dropping every single time with no solution to the problem. I have gone into the store fore assistance and that too several times, and no one can assist. They just keep resetting my router without investigating the problem. The problem is not the router but no one cares to see the light. There is a problem with the signal in the area, and there is no way to seem to get anyone at vodacom to see this and fix it.
