Customer Service - Call Centre

<p>It's been 4 months since my request to listen to a call between a Vodacom represensitive and me, they promise feedback and never get back to me.</p> <p>Worst service I have experienced from any company.</p> <p>The agents are unhelpful and never seem to get the request right.</p> <p>I always have to call them and hold on forever till someone answers and tells you they cant help you, "it is with back office".</p>
