REFUSE TO REVERSE UNAUTHORISED DEBIT ORDERS

On the 17 March 2016, I personally went to FNB Lambton to request unknown charges to be reversed, the staff made me to complete the dispute form and I signed for it, they advised me to inform the service provider of which I did and they have agreed to reverse the charges. On the 1st April those blocked debit orders went through again. From the 1st to date I have been explaining myself repeatedly and no one listens to me . On the 8th April 2016 at 16H40, I have phoned again and decided to speak to the manager, because fnb have not honoured my request to dispute the payments , but then this Tanya - operations manager started making a dialogue when I explained to her that FNB have charged me ridiculous amounts of money by honouring the debit orders that I did not authorize, then she started taking me from pillar to post, I am so frustrated. I have not signed for debit orders on the 1st of every month, however I have signed for the 15th. So tanya is forcing me to agree things I did not do. And she has a bad attitude.
