Trying for Days (and on phone for hours) to get ADSL moved to Migration Holding Pool / Queue

Been Trying for Days to Move ADSL Service *** to the Holding Pool / Queue to Migrate to another ISP. Filled in Cancellation on the Website, and selected that it goes to Holding Pool / Queue. Phoned in as there was no confirmation. They processed the Cancellation, and when they tried moving it to Holding Queue, it gave an error that said they must try later. Phoned Several Times today, each time spending over 15 minutes on the call. Each person tells me to phone another person (Billing -> Cancellations -> Technical -> Sales). But nobody can help me. Some people promised to call me back, but hours later, still nothing. We have done everything that was expected, and have spent over 2 hours on the phone to Various Telkom Numbers. Who can move the ADSL to the Holding Queue? it is extremely Urgent.
