FNB Debits my account and refuse to reverse funds

<p>I took out a loan with FNB and encountered issues making payments after about 5 months, last year in October they deducted the original instalment and when I requested for a reversal to be done I was advised that it cannot be reversed. I was unemployed at the time and they took all I had left in my bank account. On Friday 26 May I received notification that they had deducted R2,055.05 from my account, no warning, no permission from me to deduct that amount from my account. When I requested for the amount to be reversed to my account I was told that they cannot assist me. Since when is it legal to debit consumer's bank accounts without authorisation? I am left with nothing for the rest of the month and am currently unemployed. I hope to get help from hello peter</p>
