Zero Service

We moved into our new home 6 months ago. The saga to get a basic telephone line and adsl system setup was a nightmare in it's own, from start to finish it took weeks of phonecalls, instore visits, more phonecalls, technician after technician, excuse after excuse. Our line rental as a result was ported over to our ISP to try and assist in the queries of poor line quality on our Telkom lines. If it's too sunny our internet dies, if it's too windy our internet dies, if the weather is just perfect, it dies. For two weeks now we have had constant intermittent internet, 30 seconds on, 30 seconds off, 247. After a technician arrived a week ago I was told it was faulty cables that would need to be replaced. I'm yet to get a call from one to confirm when they will be doing the repairs. The poor consultants on the help line aren't able to do much more than 'escalate' the urgency of the job, but if the technician isn't calling me, what am I supposed to do? I have no internet, I cannot operate my business, I cannot do online conferencing with my daughters specialists, I cannot even check my email. What is it going to take for me to get the service for which I am paying for?????????
