Too soon celebration - FNB, Can you help?

I did reported a ***** transaction last week and even thought the case was sorted since FNB reversed my money on the following day (***** line ***), and couldn't ask for better at that moment. Unfortunately, this morning the very same ***** (reported) transaction was deducted from my account? I can't understand why? I did everything on the 6th March by immediately reporting the incidence via App, cancelling my card (ref 008500), filling and emailing the ***** transaction form, and phoning FNB ***** line. This morning when I phoned FNB ***** line to report the incidence (though it was a new one) I've been informed that it was the same previously reported incidence and the ******* now enjoying my money via that ***** Paypal incidence. Moreover I've been told that investigation can take up to 10 working days?. If the money was reversed by FNB on 06 March why it went through this morning 12th?.
