FNB FAILED ITS CLIENTS

On the 3 September I made a p from my bank account to my Mr Price account and I received an SMS to inform me that the transaction was successful. To my surprise On the 7th September I received an SMS to inform that transaction failed. I even was charged R114 for failed transactions. Where did that R200 dissappear as it was deducted from my bank account on the 3September. I really are not happy with this
