No internet for 10 days

I have been experiencing intermittent to absolute zero internet connection since April 30. MTN keeps on opening and closing the case so it seems as if the call is not being so long overdue. On Friday 7th of May it went off again and I phoned again to the coverage department, and wa spromised a supervisor will phone me back. No phoned me back. Internet came back Sunday 9th of May and went of Monday 10th of May again. I had to phone again to the coverage department. Wa spromised I will be phoned back, again no call. Social media "service champions" are no help as they tell me feedback takes 2 to 24 hours. I can't believe I need to pay for a service that is not being delivered to me. It seems to. Me that MTN doesn't really car eabout customer service. I have no. Idea why they call themselves service champions when there is no service. And if anyone will actually read this and come. Back to me I have all the evidence of all the conversations.
