Last Monday I got an sms saying my fault was fixed, so I smsed back to say it wasn't as my speeds were still stuck at 2.5mbps. Telkom phoned on Tuesday saying they're still upgrading, next 2-3 months... Which is what they said 3 months ago.
Just now I received a phone call from a Nicholas at Telkom and had a long chat. He says the congestion fault was logged in Feb and resolved in May. They upgraded from 11.2mbps to 12.mbps. I'm assuming he meant megabyte per second not megabit... No further upgrades planned. And according to their best effort service, 2mbps is good enough on a 4mbps line. Then he went on to blame uncapped, poor telkom planning, etc. etc. for poor performance, which doesn't help me much.
So much conflicting information. All I know is that there were 3 Telkom vans parked at the exchange on Sunday, so hopefully they got it right this time... I ran a few tests now and my speeds are up to 3.4mbps again, so hopefully things are actually resolved...
