Overcharged for 6 Months despite numerous complaints

<p>I upgraded my contract in July 2016 and for every subsequent month I have been overcharged.</p> <p> </p> <p>I am still being charged for my old handset fee despite the fact that I only upgraded one month early (Upgrade date being August 2016)</p> <p> </p> <p>I have phoned customer service on numerous occassions and been told that the problem has been sorted out but I am still being overcharged.</p> <p> </p> <p>I find it highly dissappointing that Vodacom, who claim to be the best cellphone service provider, have been continually de*****ing me for 6 months.</p> <p> </p> <p>I demand a cash refund for all of the months that I have been neglegently overcharged and that my next debit order is correct.</p>
