Contract discrepancies

<p>On the 26 of October 2016 I signed a contract for R399 for a data Contract, which I upgraded from my previous one, Due to my contract being ported to a business contract and the proper invoice only reflecting in December I notice that the monthly invoice for was reflecting R499, I notified the Manager of the store where I upgraded and she said she will investigate and every second week since December I have followed up with her, and she has been in contact with the Finance Commercial, Sales, Credit department, even the Cancelation and Retention department trying to get the contract cancel, an reloaded on Vodacom system under the right, amount.</p> <p>She has submitted credit notes, so the extra R100 that gets debited from my account get returned, but nothing has come from this.</p> <p>I don’t understand how Vodacom can see a signed contract for R399, and then load it as R499, and not grasp that it’s not correct, and needs to be rectified.</p>
