POPPI Violation / Breach of Contract

I have had an outstanding query with Vodacom dating back since Dec 2014. I have been into the Vodacom stores and called *** to no avail. I was only notified last week that no call or complaint has been escalated even after I was assured by the stores, as well as agents, that it had been. I downgraded an open line in July 2014 onto a top up account. The Vodacom staff member did not put me onto the correct plan and without realising it, the account ran up to R14,000 worth of data. I am more than shocked to find out that this is the issue, as I have been asking how this is possible for months knowing that it was on a top up plan. I have barred my own number only to find out that someone in Vodacom un-barred this number. My account was suspended today and my clients received a message, when dialling into my number, \your service has been suspended
