Account debited twice

<p>How can an account be debited twice??? This is what I experienced on Tuesday 04/04/2017 when I checked my banking details and to my surprise saw this. After phoning DStv and being told that a reversal will be made AND receiving an sms stating this - that the amount will refelct within 3 days in my account. Well it is now Friday 07/04/2017 and that amount is still nowhere to be seen in my account. This is very shocking and disappointing, as I received a payment yesterday from a person from another bank and it is reflecting this morning in my account. So please, I would like to know where that amount is and if this is the case about debit orders from DStv, then I will be cancelling mine and do my own payments. At least then I know that the RIGHT amount will be paid and not pay it TWICE!!! I hope that I am not the only disgruntled customer out there... </p>
