Vodacom failing to Unblock my number after blocking it.

It feels like vodacom is failing to manage or control it's system. They blocked my number due to RICA Status and requested me to send my RICA documents which I have done it in a number of occasions in their branches but still cannot unblock my number on the system which they managed to block it but now failing to unblock it. When I call and visit them in their branches they say it is RICA and when I call or SMS RICA my Status is Active. The funny part is I am currently using a Smart ID Card but they requested me to bring my Green Bar Coded ID which doesn't make sense to me because the same ID Number on my Smart Card is the one on their system. On my last visit the branch consultant mentioned that i have to changed my number since they are failing to unblock it.
