Sorry if this is somehwhat off-topic (no idea if it's been included in the complaint or not), but is there any chance of mentioning something about local bandwidth? I'm sure a number of people here (at least the gamers anyway) would have less of a problem with the 3GB cap if local traffic was completely excluded. SAIX provides gaming servers for us which I'm sure all SA gamers are grateful for, but then we have to moderate our usage because it counts toward the 3GB cap.
Seeing as local traffic seems unlimited anyway (it's the same speed regardless of whether you're capped or not), could Telkom find it in their hearts to at least exclude local traffic? I bet it would get rid of the capping-complaints for a while if they did that.
Additionally, is there any sort of formal petition or poll for the exclusion of local traffic from the cap? I wouldn't say it's a totally unreasonable request so Telkom might even consider it if it were presented to them formally and cordially.
