Unauthorised Debit Order!!!!

I've noticed three debit orders from REVOLVREW REVOLVR3675 015 from this company and these are debit orders I have NOT authorised!!! What is happening here? I've lost R118 every month? Why are you as a bank allowing my money to be taken by this company without confirming authorisation of this? I would like a reversal of all three debit orders without you guys billing me because this is in no way my fault. It's quite disappointing that this is how you operate and deal with customers and clientele and what is going to be done to rectify this problem?

I have gone online and seen multiple reviews from other customers complaining about the same matter yet no measures have been put in place to stop this from happening. I've called your customer centre which doesn't have the decency to state outright that the centre is closed but leads on a 1-minute route advising this after the fact. It's frustrating and impedes on your brand values and my value as a customer at FNB? I would like to know what is going to be done about this, when the debit order will be reversed with FNB WITHOUT bank charges, and how will you ensure that this does not occur in the future? Should I not get a fair resolution I will forward the matter and relevant documentation to the Ombudsman to deal with.
