ADSL line not upgraded within specified time

I ordered an upgrade of my ADSL line from 2M to 4M on 03/07/2015. It has not been upgraded yet! I spent an hour on the phone on 10/07/15 with a consultant telling me that there were problems with my request, but he could not tell me what the problem was or how it was going to be resolved. I spent another 2 hours on the phone today with 5 people at Telkom trying to get assistance. Only 10 minutes was spent actually talking to someone. The rest of the time, I was put on hold. I still have no resolution to my problem. <br> How difficult is it to upgrade an ADSL connection ??? It is also not acceptable to put someone on hold for such long periods of time. Telkom, your service sucks. If there was another alternative for an ADSL connection, I would change service providers in a second. <br> Who do I contact for an actual, true reason for the upgrade not being done ? How is Telkom going to resolve this ?
