Unable to access account

<p>The last call centre assistant stuffed up my data request so I am continuesly running out of data. To change back requires me to know all my account details. I dont know any of these because I have not seen a vodacom statement in about 3 years as it is not emailed to me as requested years ago. Who knows where it ends up monthly or if they even bother to send an account! So I am told to go in store with my ID number to access my acount! How primitive! Really challanges the fact they call themselves 'Service providers". Its laughable!</p>
