MTN signal and service.

So unhappy at MTN service at the moment had “no service” in the cedar fourways area for the last 17days! Can do nothing with my phone until I leave this area my complex gate everything is linked to my phone and literally can’t access or do anything I call MTN just to get a rude consultant tell me I must use my roaming in this area I tried that still no service phoning MTN every other day just to tell me the engineers working on the tower everyday with no time line after 17 days when this will be fixed!!
