I've had a pleasant experience actually

Long story... sorry
I called their 10212 number from my cell first because my telephone line was dead (cables stolen) and was connected within seconds. I got my reference number and the following day called back and again, within a few seconds my call was answered.
This time they told me to call the ADSL number 0800 375 375 which also, within seconds was answered. They told me of the cable theft and we left it at that.
A few days later I used the online fault reporting page mentioned in this thread. The next day I received an email confirming the cable theft and giving me an estimated fixed date of the 27th of this month! I used that page again and complained at having to wait that long and also suggesting I should receive a credit. Well my line was fixed on the 11th of this month, exactly a week since it was down. Telkom then started calling me back (2 calls) asking if everything is up and running and to inform me both my line rental and adsl will be credited from the time it was down to the time the first call was made from my phone which happened to be the 16th. By that time I had downloaded 4GB already

So yeah, it works and I'll continue to use it because you at least get the confirmation email and they do call you back too.
