Acount settled yet debit orders still going off no reversal of money

Hi

I bought my vehicle thru Wes Bank finance and a little bit more than a month back i settled my account and paid it up in full.

Wesbank confirmed this and yet on the 30th of the month i phoned them as i saw their wesbank installment sale account still active on my app and had to confirm whether the debit order has been canceled.

i spoke to a Sipewe who told me that the debit order has not been stopped and will go off on the 31st march i asked him stop it as he confirmed that my account is settled he said he could not but assured me that he will communicate to his management so they can reverse the payment.

it is now 7 working days later and no response from wesbank. payment has not yet been reverse and the debit order is still active.

secondly i have sent westbank proof of payment to deliver my Natis document and in 7 business days no response

i finance all my vehicles thru Westbank but am seriously considering using someone else next time
