Ongoing charges for a cancelled data contract

<p>I cancelled a data contract that was sold to me with a free wifi router on 14/09/2016 ( cancellation ref 1- ********** 9007). A courier collected the router and SIM card on 30/01/2017 (four and a half months later!). However, the contract has not been cancelled and Vodacom continues to charge me for the data contract, in spite of me not having the SIM card any longer. I was promised in February that a consultant from Vodacom would contact me, but it is now five months later and I am still being charged on a monthly basis.</p> <p>I need Vodacom to pass a credit for the data charges from September 2016 until today, but have found no way to get someone from Vodacom to respond to my requests.</p> <p><br />Pathetic service!!!</p>
