Please can someone rectify my Vodacom account

<p>So this is my second complaint ,</p> <p> </p> <p>Someone from Vodacom contacted me and said that my account would be credited for the data fee that they've charged me for the past 4-5 months without my consent.</p> <p> </p> <p>I just viewed my invoice and these changes have not been made.</p> <p> </p> <p>This is really beyond frustrating Vodacom</p> <p> </p> <p>I am truly disappointed</p> <p> </p> <p> </p>
