Vodacom unable to change contract to pay-as-you-go

I am trying to convert from contract to pay-as-you-go on ***, but being send from Pillar to post between the consumer and business segment, as I apparently are on the "old system" which nobody can or will access. If you go into a shop, they refer you to the help desk. If you call the HD, you spend 30min being transfered back and forth. Pathetic!!
