Missing data

During June and July months I had excessive data usage from my data card which could not be explained to me by Vodacom yet our bank account was debited for the amount of R3000.00 on a R99.00 subscription, I then asked for my detailed billing for June and that the matter be investigated as I did not make use of out of bundle rates as stated to me in the explanation, the call centre said they would e mail the detailed billing to me, in the interim I also terminated my data account with Vodacom giving a months' notice. At the end of July I again received another excessive account from Vodacom which caused R1000.00 to be debited from my account. I asked for the detailed statement to be sent to me as well.<br> <br> To date I have not yet received my detailed data billing as requested for the moths of June and July 2015, I have sent mails requesting explanations why the usage rates were so excessive. Why are we expected to be satisfied getting no feedback but they are quick to phone you when you haven't paid an account!!!!
