Shocking prices

Good afternoon , I am extremely upset with fnb business. Fnb have taken So much money from my account it is disgusting actually. I had to use my business card to swipe for toll gates. The toll gate charge was R4.50 yet fnb charged me R145 penalty for not having funds in my account at the time , if I use my personal platinum card it just goes into the minus . I unfortunately had to go through a toll gate 8 times on two different occasions so fnb charged me R1160 and again R1160 for the second time that totals to R2320. Now because of this I missed a debit and again I was charged another penalty of R175 when the debit was only R80 and another of R175. I have had R2300 paid into my account and everything taken from me because of penalty fees. I am extremely upset , I am a single dad who is self employed and I ask you to please pay me my money back or I will cancel this account.<br> Hoping to hear from someone. Regards Craig
