STILL WAITING FOR MY REFUND - REF ***

Even though I have a payment arrangement with FNB to deduct R1500 from my account, they decided to deducted R12 890 from my account without my permission. I have been trying for 2 weeks now to get my money back and everyone keeps saying "we apologies for the inconvenience and we will refund" but nothing is getting done. I have explained to a number of people that I no longer have a job and this money is supposed to last but no one is listening. One last person I spoke told me they can actual take money from my account without my permission. And to make matter worse everytime you keep asking for a supervisor or manager to call you back they don't bother. FNB has no ethics whatsoever I WANT MY MONEY BACK TODAY
