Vodacom, is it time for a change?

We purchased a Vodacom fibre package last year. It was pretty good until about December. Then we started having issues. Last weekend we were down for about 6 hours over the weekend. Apparently the issues was with OpenSource, dont know that. The speed was a little iffy but came back to full speed. Today it went down again, now for about three - four hours. In both cases the help desk technicians were superb, able to help me intelligently and easily, despite my irritation. However I am now doubly irritated. We went fibre because ‘it is more reliable’. You cannot prove it by me. I need access to various sites but this not happening. It may be time for a change to someone who can provide a service, hopefully there are companies who can do it. Upshot, Voadacom your product is terrible, serviced by good people who have to support this product. They have my sympathies.
