Customer service/call centre

<p>I called in to Vodacom to query missing data and as usual I was sent from pillar to post! Vodacom has the most unfriendly and *********** service call centre in South Africa. Vodacom, as a customer I would like to ask that you do some serious ups****ing in your customer service department. I was screamed at because I could not hear the agent on the other line and then the cherry on top is she hung up on me. Its interesting to me that once a sale has been made there is no after sales support, all I want to know is why I did not receieve what I had agreed upon taking? </p>
