I'm very happy with my account currently.
There have been complaints though and CW has acknowledged that there are issues and it was supposed to be resolved, but a spanner was thrown in the works by Telkom.
They are busy implementing with a workaround.
It seems it is especially the >10Mbps account that are influenced, but that is only my opinion and shouldn't be taken as a fact.
I'm on a 4Mbps account in the EC and like I said, it is running like a bat of hell.
I've had some packet loss issues that could be related to Telkom infrastructure, according to CW.
It does not seem to impact me as far as I can determine.
