Vodacom debit after the number has been ported

<p>My Vodacom contract expired on the 29th April 2016, after which i had the number ported to MTN. Vodacom debited my account on the 24 May 2016 with R1050.39. My vodacom account has never been this high in the 15 years that I have been with them. Now trying to call the call centre you need to enter a valid vodacom cell number, which I no longer have, so guess what, I cannot get though to speak to someone. I had my bank reverse the debit order.</p>
