Telkom and Vumatel - the worst combination

Telkom and Vumatel have formed an alliance to drive customers mad. A line upgrade that was sold as being painless has been anything but that. The router was delivered from Telkom with a faulty power supply but the technical people in the shops refuse to exchange this but they offered to book the router in for repairs (2 days after I received it). The ADSL line that the fibre was expected to replace was supposed to remain active until the fib re was active - not at all, the ADSL line was disconnected the day Vumatel started on the fibre. The fibre line has also been down since then - I have called Vumatel who say speak to Telkom and Telkom who say speak to Vumatel and still I do not have a working data line after 6 days, more than 20 phone calls, and more assurances than I can count that this is the other service provider's problem. If only I could get hold of Telkom I'd cancel the upgrade but sales puts you on hold until you give up or run out of airtime or it's after their working hours so you can't cancel the upgrade.
