Telkom strikes again

I reported a faulty DSL line ten days ago. My internet connection is so slow as to be almost non-existent and connectivity is patchy at best. I have reverted to using a Vodacom 3G Stick. I have had no reaction from Telkom, apart from receiving a reference number 60ATK080215, even though I have escalated the complaint. This seems to be a recurrent problem - the DSL works fine, then for no reason whatsoever it stops working. I have not been without Telkom problems for more than three months at a stretch.
