MTN LTE Service complaint.

I live in the Natal Midlands (Currys Post) and MTN advertise that they run a LTE service in the area. Unfortunately the company I am employed by have "an arrangement" with MTN for our "work from home" WiFi Service. It's utterly pathetic and completely unreliable. Just shocking that MTN can allow my business to suffer in this way. Same as Eskom, MTN do just not give a damn that SA business suffers because they can't keep their service consistent.
