charging me extra banking fees

I changed the date my banking fees should be deducted. Supposedly in the 6 days between the 26th of May and the 1st of June I was charged a pro rata amount. I phoned the call centre (***) to hear whats up. The consultant informed me she will look into it, but that only the difference would be deducted this month. The full amount still went off. I phoned again (***) spoke to Candice who spoke to Meek Bonginkosi to hear that their system isn't faulty, its just how it is. When I change my date I pay. So this month i paid extra on my banking fees. I am sick of this bank. I have to phone you guys ten times to change dates, i have to double check on my fee schedules. We as FNB customers just don't have any control over our accounts! You guys can just reach in and take money as you please! Without informing the customer?! I don't want some consultant phoning me explaining this s.h.i.t the same way again. FNB is a joke. I pay fees on top of fees for what?! for you people to not do your ****** jobs. For your shoddy system? And then you increase the fees as well! Someone should sue FNB for for false advertising, because they don't help anyone.
