Poor service delivery

We moved into our home in October 2014, we arranged months in advance for it to be done on the 1st of October. On that day we were told that there were problems on the line outside, and another technician must come out to repair it - TWO WEEKS later that was done (following numerous calls to them), but the problems did not stop there. <br> <br> We have reported faults at least once a month, and every time we have waited up to 2 weeks for a technician to arrive ~ then the problem is 'fixed' for a while, then back to more of the same - either the internet line drops, or the phone line dies - the one works but not the other. The latest fault was reported at 09:30 (ref 147CWK160315) on Monday 16th March, with a response to say that Telkom will try to resolve the problem in 2 days, I've also escalated the issue on their website last night, and yet to have any response from Telkom! For all the time that we're not able to use the service, we're billed as if we were.<br> <br> My wife works from home and the problems are badly affecting her business, and we are considering moving to another supplier - any suggestions will be greatly appreciated.
