Where is the signal?

There signal is utter useless. Despite numerus attempts to address this matter with Vodacom nothing has happened. They just give excuses, stating it could be my device.

I have checked my device and nothing is wrong with it and also seems strange that its not just me but my table signal and other family members that also have the same problem.

I am considering changing service provider hence I am due for a upgrade, no other can be worst than Vodacom.
