Incorrect billing, call centre operator cutting tha call because they can't fix the problem!

<p>I've been billed incorrectly, for my cellphone account on my latest invoice.... Trying to get an explanation from Vodacom is useless, because the call centre operators just cut the call when they can't explain/fix the situation...everytime I call back I get a new agent, and have to start from the beginning explaining the problem and verifying my identity....just to get cut again!!!</p> <p> </p> <p>I am at the point where I am considering terminating all my contracts with Vodacom, In December I was billed for an upgrade that I did not received...Then received items incorrectly (which they still have not sorted out) In January one of my contracts was migrated from pre-paid to a post paid contract without my knowledge/request...And now I'm being double charged for one of my contracts!!!! Why is everyting a struggle with Vodacom, how can this type of incompetence be acceptable????</p> <p> </p>
