faulty line and adsl just not being fixed

really bad month with Telkom in January 2016. Arrived back and internet down. Took more than a week too restore service. Then Line goes dead and take 5 days to restore service. ADSL service supposed to work at 8mb and did more most of last year. now only works at 2mb for the last week and internet connection keeps dropping. Now phone line goes dead again. Raise a case and when I follow up 5 days later I get and sms that the case has been closed and meanwhile the service has never been closed. so I log a new case and then follow up a couple of days later to be told that it is \with the engineers\" so I ask to whom I can escalate to which I get given a complaints line as ***which is does not exist. Very frustrating and of course no refund for un-provided service line callmore and adsl non availability"
