FNB ***** department

i was hacked on Friday by 3 charges amounting to R3849.00 through paypal. i had R900 on my card left and FNB let them take over and above that with no issues at hand, i have never owned a paypal account and can understand why it went through, i have been calling non stop since yesterday(monday) and today to get feedback but the line just is on hold. I have officially used all my contract airtime getting through for nothing! even a call back from the ***** line made me wait over 30min. no one has bothered to give me any updates how or why they could steel so much funds. they wont even reverse it. this 7-10 working days to reveres a ********** transaction is **** poor. NO ONE IS WILLING TO HELP!!!!!!!!!!
