Im a customer of fnb and i use my debit card to purchase, and i received an sms from fnb telling me they are aware of duplicate of purchase from my account and then last week they reversed R433.00 from foodlovers market, so today they debited my account with the same amount, so now i owe fnb that amount, at the first place why did they reverse the money and now i owe them, kindly resolve my problem because my account now is -437.00
