Debit Orders - not going off correctly

<p>My debit order didn't go off on the 15th of June, but it did go off on the 30th of June. I wrote an e-mail asking them to check the system as I keep on getting messages that my bill was not paid. After giving them the proof of payment and asking them to rectify it on their side - they send me an e-mail saying it could take up to 7 - 14 days to rectify. This is bull****, because now they tried to debit this months account as well as the amount that hasn't been rectified. My other debit order won't go through if they take double the amount they ought to. I am looking to take out another contract, but will definately not use Telkom if they cannot even sort out payments made. I will not let them take another sent from my account before the amount paid is rectified.</p>
