Settlement Amount Debited though was manually paid

Greetings<br> <br> After cancellation of ***, I requested to cancel the remaining line. Paid on ***4 called at the end of the month to cancel.<br> Process was successful but now there is a debit order every month end on my account since end of 11/2015. For how long should I keep reversing the transaction? What will happen if there is no money in my account, and who will be liable for penalties on failed debit order?<br> <br> Kindly stop and note that the POP was sent to Retentions & Payments e-mail's - Calls made nd no resolution has been achieved.<br> I even blocked debit orders early January but they have managed to process end of January one...<br> <br> All I need is that these guys should remove my banking details on their records, trace the payment made because I used either one of the numbers as the reference.<br> <br> Ek se, that is not Ayoba at all.<br> <br> Warm Regards<br>
