Non existent customer service

My ADSL line went dead more than a week ago and after numerous calls to the Telkom call centre it was established that a system upgrade is causing the downtime. Therefore without ANY notification or the necessary support Telkom just went ahead and disconnected me. Eventually a week later when the actual system upgrade was done a network fault occurred which left me again without an ADSL line. This time over a weekend at month end no Telkom technicians were available to assist with the fault. I was promised by the callcentre that someone will phone me on Monday... obviously that did not happen. After more calls they still cannot tell me when it will be fixed. This is without a doubt the worst customer service ever!!!!
