Telkom is Useless

I have a Mbps fiber line and was informed by Telkom that i can be upgraded to a Mbps line, i agreed and was told it would take 48 hours and it was a seamless upgrade. Since the 6 Feb i have no internet and when i Call the call centre it tells me that is because of the pending upgrade that the internet is down. After about 180 mins on the line with various people form the useless call centre no one can tell me when this will be resolved.. Seamless upgrade which should be called Useless, i wonder if i can switch my ISP now, betting that this review wont even get a response from Telkom... anther state run department
