Debit Order not taken on the agreed date

<p>I have been paying DSTV via DEBIT ORDER for years now. There was a consultant who called me, she told me she needs to update my Debit order due to their system was updated,i told her to debit my account on the 20th of each month as its been for years. My account number never changed since i have been paying since 2006. My account at 11 Vygie street ON the A2 has been suspended every month and that is not my fault as they were instructed that the debit should run on the 20th and not 22nd as per agreement.</p>
