Do not switch to FNB

On the 23/03 I logged into my FNB internet banking and a notice popped up claiming that I qualify for a pre-approved loan of R5200. I accepted - BIG MISTAKE! The money reflected immediately in my FNB Platinum cheque account. All of a sudden on the 26/03, without any notice, an amount of R3611.89 was deducted out of my account by FNB stating \Short term loan repayment". Again on the 30/03 the same thing- this time the amount was R2212.11 \""Short term loan repayment\"". Within a week FNB stole an amount of R624.00 from me"
