Vodacom is still deducting my account for cancelled contract

<p>Expired contract not cancelled as per telephone discussion</p> <p>I phoned vodacom to cancel my contract on the 09 March 2017, as it will be coming to an end April 2017. I was told the last debit order will go end of April but to my surprise my contract was not cancelled as per discussed. They have top up my number airtime on the 1st may 2017. i phoned again on the 1st may to ask about the airtime. they apologized and took back their airtime but to my surprise today they deducted R208. and when i phone to ask i am not getting any answers or explanations why </p>
