Useless Service provider

Literally am having the worst experience ever with vodacom, 2 weeks ago I encountered an issue as my services were blocked, reported to their customer service department to which they told me it will take 7 days to get back to me regarding the unblocking, what grates me is this line is prepaid and was used for business, ti date this line is still blocked and they have not had any decency in contacting me, the impact that this Has caused due to many of my clients not being able to get a hold of me has been disastrous,
