ADSL profile being halved without consent

Every few days my ADSL profile is changed from 4Mbps down to 2Mbps, so essentially it is halved. I have to call the call centre to ask them to reset the port and also change my profile back to 4mbps. Sometimes the calls are close onto half an hour. and this is happening all too frequently. It is not an issue with the distance to the exchange, because that was tested, and it all worked perfectly before. I know of many other people that are having the same issue, and they live in different parts of the country. So it is not an issue with distance from the exchange. <br> I think that it is only fair that Telkom upgrade my profile to an 8mbps one, so that when the profile downgrade happens, my link will then be a 4Mpbs link, which is what i am paying for.<br> <br> I cannot tell you the frustration this is causing me, and a whole lot of other people. to have to call the helpdesk every few days and waste half an hour to sort the issue out just shows how NON Client Centric Telkom have become.<br>
