Telkom's rude and *********** service

I have had a fault with Telkom since the 03/02/2016, I have had speeds of 0.60Mbps on a 4mbps line. I have been told that the matter is being resolved and its been escalated to Team leaders. I call on a daily basis and yet still no solution or an answer. Today at 10:30 one of the consultants dropped the phone on my ear, I feel that is unacceptable and is simply just poor service. I have had poor internet for over 2 weeks.
