Not updating Billing after Migration of ADSL

I requested a migration of my ADSL line to MWEB (after spending numerous hours waiting calling the Call Centre). MWEB's service in this regard was quick and efficient and the migration happended (and I was notified throughout the process by them) soon thereafter. They updated ther billing to include the pro-rata billing for 20 July 2015 to 31 July 2015. Telkom has not updated their billing after the migration so in effect I am paying double for line rental. I have been trying to get someone at Telkom to assist me to rectify this but I have been transferred to various consultants (waiting for service on a average of 30 minutes per transfer). This is really bad service. I do not understand why MWEB can be so efficient and Telkom can't even get me the right person to speak to. They also do not respond to emails sent days ago. My migration reference is ***9A. I could probably leave it and pay double this month, but I am pretty sure they will probably charge me for line rental next month again. So I am forced to stay on the line to make sure they update my account with the migration. I am really disappointed with the service from Telkom, not one good experience to date.
