I made a decision to ditch Telkom totally and so, despite the few problems with iBurst, I will stay with them. It took Telkom four months to process and complete an analogue to ISDN upgrade. Then it took almost six months for them to upgrade ISDN to ADSL. Their excuses were: I did not apply for ADSL. I applied January 2005 and contacted them in March 2005. I quoted them the order number. Then they said that there's no ADSL in Montana Park. I quoted the neighbours and people I know in the area who have ADSL. By this time, now July 2005, I had had enough.
For me it it now a matter of principle. I am glad that iBurst now allows you to use your own SMTP server. This was not advertised anywhere though. Luckily I have copies of all the mail I sent yesterday and my clients are understanding in this regard. There's no way I will ever want to have anything to do with Telkom again. I will rather wait for the second operator, even if it is more expensive. And even them I doubt if it will improve on the service I now get. Sure, yesteday was a problem, but it's the first time. Any my iBurst connection still delivers better results as ADSL clients in the area.
