Oranjevallei no signal

You suck. Plain and simple. We have absolutely zero signal in Oranjevallei outside upington. Went to do a Sim swop today. Not helped. Try calling your service centre for mtn. They just said that they are out of office hours. Every person I asked having mtn said they have the saim problem. Vodacom and cell c not affected and working perfectly. No help from your company.
