Vodacom Fibre the worst pathetic service ever!!!!!

Getting the worst service from Vodacom Fibre. They have been double billing all of a sudden for the past 3 months. I raised this problem over a month ago and noone seems to be resolving this issue, everyday I get thrown from one consultant to another with a new excuses. Now my line is suspended and I was forced to make another double payment while they still can't resolve this issue and I am still offline as I write. Vodacom fibre service is pathetic and taking it's clients for granted. Who is going to refund me for the days I am paying without service???
