Telkom misleading customers on number porting

First I would like to quote from Telkoms promotional literature "Your number is yours. You can't be penalised because you want ot move (port) your number across to a better alternative." Why the after having my number on a telkom SIM card linked to a DSL account for over three years I am told, at there customer centre, that my number is locked and cant be released for porting!!!! This happened in mid December and, despite the matter being escalated to a higher authority who promised to look into it, I am still blocked. So, as it stands at the moment, if I want to use my number I MUST reopen my account with Telkom. As far as my knowledge goes that is called ******ion!!!
