Vodacom Unauthorized National Data Limit Lock Deactivation

A lady from Vodacom (+***2) called me just now and asked if I would like to deactivate National Data Limit Lock which is a new customer protection regulation from the Independent Communications Authority of South Africa (ICASA). I told the lady that I cannot understand or even hear some of what she was saying. I asked her to please email the proposal to me and gave her my email address. She did not email me anything. Exactly 32 minutes later I received an sms stating: "Your National Data Limit Lock service has been deactivated." I did not agree to this. I own a company and have seven mobile accounts with Vodacom. Please be aware of this **** whereby Vodacom is overriding the authority and new regulation of ICASA and automatically deactivating without your consent.
