Vodacom terrible service

<p>I upgraded my cellphone contract, but Vodacom incorrectly changed my tablet contract. We rectified the problem by resigning a new contract. 3 months down the line they are still deducting the increased incorrect amount. Still no refund after various requests. The person that initially helped me, now resigned and now nobody knows what is happening. I am fed up!!</p> <p> </p>
