Worst billing for the past few months

<p>for more than 3 months I am being billed incorrectly. I go through rigorous and not so user friendly Vodacom call centre. </p> <p>After at least being on the phone for more than 20 minutes, the consultants always tell me that "I can see the problem with your account but I can't fix it from my side, you need to contact such and such a department."</p> <p> </p> <p>this has been going on for months without end and the bill keeps up. I've sent emails and to be honest, maybe terminating my contract and returning the handset is the best option.</p>
