Telkom changing profile from ADSL to VDSL

I've tried for 3 hours to change my DSL profile from ADSL to VDSL. Nobody at Telkom can assist me, they keep transferring me to somebody else. Had to phone multiple times as well as the line sometimes just goes dead after holding forever.<br> <br> Also tried the online chat with no success. My line speed was increased quickly from 10Mbps to 20Mbps which was good service, but I can see that it is still syncing on the ADSL profile.<br> <br> I'm still on the phone hoping that someone can assist me.<br> <br>
