I want answers! Disputing ********** debit orders

On 13 February, 13 March and 14 April, Loan finder SA has **********ly tried to debit my account each time. I have never been and never will be a client of Loan finder SA. I tried to resolve this directly with Loan finder SA, but they aren't willing to stop their ********** activities either. In March, I lodged a dispute for the first two ********** debit orders that bounced and I was promised feedback by 30 March. I have yet to receive any feedback and since then a third ********** debit order has bounced as well, which could affect my credit record. I'm LIVID right now. Why can't FNB stop these ********** debit orders and refund the unsuccessful collection fees?!? Or are FNB just happy that they can profit out of *****?!? I've tried to follow the correct processes but have received no joy - even lodging a complaint with the Payment Association of South Africa. Is it because the ********** haven't managed to debit my account because the debit orders bounced each time?!? I want to lay ******** charges against Loan Finder SA, but have been unable to since they refuse to supply me with the name of the telemarketer who committed the *****. PLEASE HELP!!!
