In other words, you misused the phrase 'raise some noise'.
And no, I am not wholly misunderstanding what you are saying. I also went on to agree that people with an actual issue need to at least report them. As for there being no data, I'm fairly confident that it's wholly visible when someone that normally downloads, say, 80gb a month on their 1-4mbit line, phones in and complains that for an entire month they have had wholly poor speeds regardless of account type, network or source of traffic.
As for the 'continues to neglect' and 'take it to ICASA' thing;
If you want to raise some noise, then create a(nother) Hellopeter petition and get as many people as possible to sign it. Despite how useless it is in reality, it would be infinitely more useful if people are signing a petition regarding the same issue that is known but goes unaddressed than 'raising some noise' in stores or on the support lines would be.
Telkom has neglected to address, in a timely manner, issues with their internet services for, at the very least, 9 years now. Various bodies have 'taken these issues to ICASA' over the years, and the result has always been the same.
Telkom says there's nothing wrong and/or gets a marketing guy to try and convince people that they've been improving their quality of service and consistency when, in the overwhelming majority of cases, the specific situations they are addressing demonstrate facts to the contrary.
So yes, if people have an issue that can be resolved by phoning tech support, then by all means, phone tech support, get your (almost always useless) reference number, and hope that the chain of people handling a ticket will actually get around to sorting that issue out.
Do not however expect 'raising noise' to achieve anything with Telkom. They have shown time and again that they are even happy to lose hundreds of thousands of users utilizing their ADSL connections, where those customers are going off to significantly more expensive yet more reliable methods of connectivity. As far as they're concerned it's pretty much a non-issue if there are long-lasting major issues.
Look at the Overberg area; after 3-4 months of people all over the region complaining about practically unusable connections during the daytime, they finally managed to get *something* right; now our connections out here are only really slow, but at least usable, during the day on weekdays. The quality of the connections is still not nearly where it was a year ago in this area, though, and while all of this is happening Telkom is even trying to trial 40mbps DSL in parts of the country. This, again, while their previous trial of 20mbps had limited penetration and worse still, while their proposed '4mbit users will get a free upgrade to 10mbps' thing has seen extremely limited penetration.
If you want to raise your noise, then do it in a direct manner. Get that petition going and take it to ICASA. Go and fight your fight to see how futile it can be to try and get ICASA to gain the power to do something about Telkom.
