Thanks for your honest reply! It's just that my ADSL line is so shocking - apparently due to faulty cables in the Rondebosch area; my speeds are generally 1.2Mbps DOWN and 0.1Mbps UP on a 10Mbps CAPPED line and it's intermittent as anything, as too is the landline! Telkom haven't sorted that out since I logged the fault on 19 June (surprise, surprise). Any further information or update about the Fibre roll-out/approximate live date would be greatly appreciated!
I had the exact same problem and was also told I was too far from the exchange to expect anywhere above 4Mbps. Then one of my neighbours (on whose property the telephone pole resides) destroyed the line to the pole in the process of doing renovations , which meant Telkom had no choice but to come out and lay new copper. After that I thought I'd try my luck with their 10Mbps offering and what do you know, I now get a stable 9Mbps.
(You might be asking "why do you want fibre if you're already getting 10Mbps", the answer is that 20Mbps fibre with the same cap will work out cheaper monthly than ADSL. So why the hell not?)
As for ADSL line issues - I have heard first-hand from the mouth of an OpenServe technician (all of whom are ex-Telkom techs) that areas where fibre is installed or being rolled out are being "deprioritised" for ADSL maintenance. Translation: if you're in one of those areas, Telkom wants you to upgrade to fibre and they're willing to "encourage" you by ignoring ADSL issues. I do kind of agree with them (why bother upgrading or fixing old and broken copper when fibre is faster anyway?) except for the fact that they've botched the fibre rollout, surprise surprise - I'm just holding thumbs that
my damn ADSL line doesn't die before they get my fibre sorted!
So you're probably in the same "deprioritised" boat, with the added f**kup that you're already on old and broken copper so there is even less incentive for Telkom to do anything about it. Unless you are willing to deal with Telkom's call centre, or actually take an hour out of your day and wait in line in one of their damnable branches, there is sweet f'all you can do.
Except... there is a way to circumvent that nonsense. There is a member on these very forums,
TelkomZA to whom I have turned in the past when the standard avenues have failed - and s/he's come through for me every time. So drop him/her a PM with your tale of woe, and hopefully your ADSL will get sorted out - as for OpenServe fibre, I don't have any contacts unfortunately.

It seems like fibre is being wholly managed by the ISPs with the actual infrastructure providers having little or nothing to do with end-users, which is good because it means the (hopefully more responsive) ISPs will process queries faster, and bad because it means there's an extra layer of broken telephone between me the user and the actual fibre provider when (not if) s**t goes south.
I can tell you that from personal experience with WebAfrica handling my fibre install, I'm certainly not seeing any benefits of making the ISPs responsible...
