FNB UNAUTHORIZED DEBIT ORDERS

I am really disgusted by the service I got from the FNB ***** and Debit order dispute consultants who were transferring me to and from each other. I have been getting unauthorized debit orders from a company called Legaleye, Mediaassist,unitedrew, & rescue 247 from the 30th of November 2018, I stopped the debit order on their "app" that is suppose to make our lives easier for efficiency and quick assistance but these companies (which I believe is one company) tried debiting my account on the 15th of December 2018 again, fortunately I moved my funds from my account which is why the debit order went through as unpaid, however my account is now in arrears. I believe that FNB ***** team should have been aware that there's a **** going on of unauthorized debit orders from these companies because its well known and should have taken measures to ensure it does not affect its customers, now I am left with arrears in my account & unauthorized debit orders that are constantly going through, I am afraid the second my salary gets deposited in my account funds will disappear ; firstly because of the arrears and charges that are accumulating & secondly because these debit orders will continue. I told the consultant to stop these with immediate effect, she proudly and confidently told me to take it up with the company. My question is this 'How the hell do I take it up with the companies I have never even spoken too or given permission to debit my account?' I cannot trust FNB with my funds because they just allow any debit order to go through without any proper validation which means they still lack the means to offer their customers 'security' from where I am standing this is on FNB for failing to protect us 'their customers' from ***** and ****s. I want this matter sorted out, the point of you going digital was for us to be able to resolve and get assistance on most of the things digitally so that we can save time and avoid standing on queues etc, I do not want to come to your branch I want this issue resolved or I will take further actions concerning this matter. This is the worst customer service !!!
