Vodacom NO INTEGRITY ,TRANPERANCY OR HONESTY

Vodacom has no transperacny or integrity.I spoke to an agent about cancelling my contract as my term of 24 months ended.The agent then spoke to me about minutes that would cost me R89 a month only nothing more and nothing less.Today I called the call centre and the amount is a whole different amount which I did not agree too NOR DID I KNOW ABOUT.I am sure the ombudsman can help if VODACOM REALLY WORKS ON NO PRINCIPLES!!!VODACOM can you get the recording of my conversation with the agent as it was clearly stated the the only amount to be deducted would be R89.
