Terrible Cell C reception/service in Potchefstroom

I recently ported from Vodacom to Cell C on a new contract. I wish I could turn back time.<br> <br> No one is ever able to reach me...most of my calls get diverted to voicemail but my phone is switched on. Data is also very slow. Phone often shows \NO SERVICE"...that says it all.<br> <br> I use my phone for work and it is crucial that colleagues are able to reach me. Fix this or I will have my attorneys cancel the contract for breach by Cell C."""
