Vodacom service stinks!

Cancelled my contract to be moved to prepaid which went through well then cannot be signed up for the Powerflex deals because my number is still showing under a contract profile even though on prepaid. This is now the third day going back and forth with consultants who even suggested the *135# menu which is useless and they end up saying they will call back after waiting and waiting while they speak to their supervisor and it gets nowhere! Vodacom owns the service but they do not know their own service. The walk in centre at Gateway offered no help because it’s an online service and the call centre has no idea. It’s pathetic!!
