Telkom's customer service has improved dramatically over the last year or so. If I phone to report a fault, before the call is ended, I receive an SMS with the reference number. The problem is usually resolved within 24-36hrs, which is a vast improvement.
I'm not sure many of you recall what it was like 10 years ago, when it took 2-3 weeks just to get a technician out just to come and have a look at the line, let alone fix it.
The very next day I get a call from Telkom checking whether the line is working.
Telkom are on the right track with their customer service, however, I feel they need to focus more on their products, i.e. higher caps, and higher speeds
