Wrongful billing and lcoking of acount

Vodacom added a data bundle charge to my account which I did not authorize and then locked my account for being in arrears due to not paying for said bundles.<br> I have a topup 590 with the sim in my ipad, I use the airtime to buy a 5GB promo data bundle for R399 each month as a ONCE OFF bundle. They went ahead and loaded a montlhy bundle on my account to be added above and beyond the costs of the contract.<br> Upon realizing that my account balance was higher than normal I contacted VC and logged a request to have the charges removed and the consulted said I would get an email reference number via email or SMS to follow up on my request. This never happened. I subsequently requested cancellation quotations to all of my accounts and was told that I couldnt get one for the account with dispute logged on it as it was still under investigation. VC then locked my account and proceeded to call a friend telling her that I had to call them back due to my account beig in arrears which Im pretty sure is not LEGAL for them to do. I used to work for vodacom in subscriber collections and happen to know exactly what their procedures are. And it is never about rightfully helping the customer
