Poor signal Vodacom

After trying for a couple of weeks to get hold of the correct department, I finally got contacted by the network department on 26 January. I was told that they would send someone to test the signal (if they can find one!) and possibly give us a booster I am still waiting. It is apparently a known fact that Vodacom's signal is very poor in our area (according to MTN and neighbours).. Why are they then trying to delay it? We are most defenately changing service providers asap.
