Exchange upgrade

I moved into a new house 2 months ago in lorraine. For whatever reason my telephone line was installed on the theesecombe exchange and not the lorraine one. <br> <br> I am wanting to upgrade my 4mb dsl line to a 10mb line as they have a great offer available. I have been informed that the theesecombe exchange cannot supply a 10mb line. With all the network upgrades that Telkom has done. They have overlooked this exchange time and time again. <br> <br> How can you be rolling out 20,40 and 100mb lines when I can't even get a 10mb line. I have inquired twice and twice I was told they would get back to me as to when this exchange will be upgraded. This is unacceptable in today's markets. <br> <br> Get off your backsides and upgrade your exchange. How long am I expected to wait! Your lack of capacity is not my problem.
