Vodacom fails to clear ***** debt but blocks line

My contract was **********ly upgraded in November 2014. The ***** department confirmed the ***** in December and initiated clearing the debt generated by the *****. Only the handset amount was cleared leaving the data usage outstanding. Data usage credit note was apparently created but is not processing through to reflect on the accounts. Account went into arrears. Calls/attempts to get this outstanding amount cleared from my account were not successful. My line was subsequently suspended.<br> <br> To date I have made more than 20 calls to get this resolved, more than 4 service requests created. Almost each call sees me being passed from one department to another, 3 or 4 departments per call with no solution. With each call I speak to a new person who have a different understanding of what needs to happen and end up passing me through to another. Spoken following departments: Customer Care
