Internet Line Speed

I have had Axxess to handle my ADSL line for about 3 years now, I never really had much off a problem, until I have upgraded my line to a 20meg line and that took a day to get activated, I wasn’t to happy about that because there wasn’t any notice to say 1 to 7 working days, I have upgraded my data also from 8megs to 20megs and that was done instantly. So basically I had the line speed of 8megs and 20megs data line speed. But the main issue I have is, a day after I upgraded my line, Axxess sent me an email saying they where upgrading my line from 8meg to 10megs, I didn’t think much of it because I thought they would see I have upgraded to 20megs, BUT that wasn’t the case 2 days later I see I’m back to 10meg line speed, and it was a Holiday on Friday and now I must wait till Telkom decide on changing my line speed again. I don’t understand why my line speed was dropped back to 10meg and it’s really frustrating, I have phoned and email and logged faults on the 30th April, and I’m still waiting. It’s sad that this day in age with the technology we have today, it takes so many days to resolve this issue of line speed.
