Poor customer service from Vodacom

<p>A ********** upgrade was done on my account in August, I sent through all the requested information via email and to this date I have never got any feedback, I sent follow-up emails, I called customer service and still no one was able to help me. what's more frustrating is that I am getting calls from Vodacom telling me I owe them and every month I have to tell them there was a ********** upgrade donee on my account. I am very disappointed with Vodacom and I will never refer anyone to them.</p>
