********** contract line added to my account

I received a high data usage notification sms on 01 June 2015. I immediately phoned vodacom to query the usage as I use Wi-Fi at work during the day. The cost was more the 4X what I averagely spent monthly. Upon making that call I found out that there was an additional line that had been **********ly added to my contract which I also queried.<br> <br> Besides both queries the data usage and additional line my account was debited for R 7161.91 at the end of June 2015 without any feedback to me. When I called vodacom to query, no queries were logged so I again requested for it to be done. I immediately reversed the unfair debit. I later received a \take it or leave it"offer to have the data cost reduced however the total amount remained extremely high.<br> <br> I repeatedly called vodacom to follow-up & have the matter resolved but each time I would find the calls are closed without feedback to me. Vodacom Centurion also tried to assist. I have been told to make payment arrangements for the amount including the ********** line which is still part of my contract. Monthly subscriptions and data costs continued to be charged on my hard-locked account increasing the debt monthly. Can some one assist?"""
