Pathetic services premier banking se kaak

I had a loan with FNB through FNB easy loan from 2012, So now in April 2014 I lost my job and I informed FNB that am longer working and I was advised that as soon I got a new job I should make arrangement to pay a loan account, I started at my new job last month of April 2015 I then went to the FNB branch to inform them that a now working they activate the loan account so that I can continue paying. the gave me some documents to sign that I acknowledged that the installment of R1780 will go through on my debit Oder day wish the 7th of May 2015, on the 7th nothing went through its unfortunate I was not around I was in Moria at time so I couldn't access anything, I then thought maybe it will go through on 15th of may suprised surprised today on the 12 may 2015 debit went through R6600 out of my account almost the whole of my salary is gone, how must I supposed to survive? I call the ****** call centre that they claim is premier banking I went through this unprofesional incompetant wish I don't even know they fit and proper to do they job and they claimed that they are managers at FNB legal department (sipho Dlamini and Emmanuel ntshangase) wow that was pathetic and misleading.
