Poor customer service

I have been experiencing problems with my adsl for the passed month. It started when the line keeps dropping every weekend. I had to call the useless call centre at least twice every week until eventually a technician was despatched. He found no fault on the line and no fault with the connections at my place and after checking the exchange he called to say that everything is the way it should be. After a few days the line suddenly came up and I thought the problem was resolved.

Yesterday morning I noticed the the line had dropped yet again. I called the call centre and a fault was logged. Thankfully the line was up this morning.

Now my problem is that nobody seems to have an explanation as to why the line keeps dropping and I am being refused to speak with someone senior in the customer service department to escalate this matter and find out what preventive measures have been put in place if any.

Telkom offers the worst customer service than any other service providers I have ever dealt with.
