Telkom Fibre Extemeley Slow

We signed up for Telkom fibre uncapped 10mb/s as of 1 September. Since then we have had endless problems with the line speed and have reported this daily. The following is a summary of the problem; 1) Our number was linked to a faulty exchange, this exchange has been faulty since MAY, and our number was still connected to it even though Telkom new it was faulty. 2) Since getting the Fibre, we are yet to receive download speeds that go over 6mb/s. 3) 70% of the time our line speed is below 3mb/s and goes as low as 500kb/s. 4) I have been following up EVERY DAY!!!!!!!! The answer is ALWAYS the SAME, EVERY DAY -The technicians are currently attending to the situation -You are not the only person experiencing this issue -We will ESCALATE the issue (I HATE THAT WORD) - HOW HAS THIS NOT BEEN SORTED OUT SINCE MAY?!?!?!?!
