********** Sneeky Fees

On the 27th of August 2018 4 debit orders were deducted from my account just hours before my sallary was paid into my account. My sallary got paid then the next day FNB unpaid all 4 debit orders charging me R400 in penalty fees when there was money in my account. To make it worse these debit orders all amounted to R600 and FNB took R400 in penalty fees. This is ridiculous what kind of a bank does this? Please FNB give me back my R400 this is ridiculous, I've been a loyal customer for more that 9 years and this is what i get?
