Intermittent service

A caller was logged with Telkom last week in regards to adsl loosing conetivity on a daily basis. A technician was sent out to rectify the problem and was advised the problem was resolved. But the fault was still prevailing...call was the supposedly escalated but when I called yesterday the call had been closed and had to be reopened and escalated again. Which Telkom is now telling me to wait another 48 hours. I am paying for a service that I cannot use which is unacceptable
