MTN disappointing me, again.

I'm so frustrated with service of MTN, I've been trying to call in to them for the past two weeks, but I can't get through, it cuts off no matter what device I use. I'm being billed insurance that I cancelled last year August, also, I have an additional line which is also being billed insurance that I never signed for. I have sent numerous emails to customer care, since last year, and I must say, the help/service is below par, I don't know what to do any more :-(.

I want MTN at my funeral so that they can let me down one last time :-(, :-(, :-(...
