MTN No coverage

I am an MTN subscriber. At my residential property in Hout Bay, I receive little to no signal so I can not make or receive calls. I have called MTN Coverage on *** several times to have the problem resolved, the call centre agents are most unhelpful, they tell me to go to the area where there is no signal and call from there so that they can test if there is a problem with the tower I am connecting from. Really!? If I could call from that location I would have no problem in the first place! Other call centre agents have told me that the problem is with the Camps Bay SAPS tower, that tower is about 15km away and there is a rather large mountain between us. When I ask them how long it will take because this problem has persisted for months, they tell me \Hours or days or months"! The only thing the call centre agent have in common is that they eventually hang up on you forcing you to start the whole process over again"
