kloof branch useless

I have a business account with kloof branch and for second time within a month i lost R19210.00 from my business account and to date i have not received any assistance from fnb disputes or my branch. On the 29 January I had R7210.00 debited from my account using a blocke/****** card details for my business account. I contacted fnb the same day to reverse the payment as this was not authorised by me and my card that was ****** and stopped months ago the same details was used to deduct the funds. They contacted the merchant and thereafter allowed the merchant 30 days to issue a voucher. What the hell i am their client its my acc and funds that should be considered i am the client of fnb and to date i still have not received a refund neither feedback from disputes they are so useless. As for kloof branch they must close down the attitude from Vishen sucks hes doing me no favour as for Usha thats no better she always promises to get back to you and never does until you follow up. Our moneys are not safe in our own account as long as u bank with FNB they are the most unsafe bank to deal with. They actually allow a transaction from a blocked / ****** card that sucks. FNB worst bank eva
