Cell C worst service provider in Fourways

There is not a day that passes without me experiancing multiple phone call drops, loss of signal or just no signal at all. This is fourways, Cell C it is a city.. nobody should struggle this much in any city. If other networks can manage in rural areas, Fourways should not be that bad to manage. Get it right or I am changing to another service provider as soon as my contract is expired. Come now Cell C it cannot be that difficult!!!
