******** People with **** ***** debit orders

My account has ********** international transactions that I'm not even aware of. They debit 20 times over the last 23 days which resulted in my account having bank charges of over R3000. I have never in my life seen or heard of Bank charges worth that amount. I went into their branch and was told that they can't do anything, I called their so called Premier Banking line as Premier Bank account holder and was told the is nothing they can do as well. While me and my family are suffering because half of my salary was taken away from me by my bank. Fnb is the biggest ******** bank and company in South Africa. I have never received such bad service in my life and honestly feel like the EFF should burn down their branches like they did with clicks.
