An Unathorised debit upgrade

Vodacom upgraded my data contract on 30 January 2015 without my knowledge. They decided to debit more funds on my account on 28 March 2015. Was advised to log a ***** query with them which i did on the 7 April 2015. Today being the 5th of May I decided to call their ***** line and I was told that my query has not been actioned as yet but it will be done today. I am very disappointed that through all of this my contracts with vodacom are blocked and I can not use both my data contract and cell phone contract. I was told by the agent on the 7 April 2015 that it will only take 48 hours to fix it. 48 hours turned to a month.
