Worst service ever

I am now on day 9 without data service. The response of Vumatel is by far the worst I have ever experienced. There is zero communication and blatant lying to just get me off the phone and so far not one assurance of reconnection has been met. It is so bad that they cannot even get their story right and keep contradicting themselves every time I phone. I spoke to a supervisor Glen who promised my problem would be sorted a that day or at the latest the next morning and when by chance I got hold of him again he gave me a completely different story as he had forgotten what he had told me on the previous occasion. Completely unsatisfactory
