Frustrated and very unhappy

Im so frustrated with FNB on how they deal with customers and just take and take money from them aswell as your bank charges. I send a compaint and got a email back saying " An investigation into your matter will now be initiated and we will be in-touch with you shortly. Its been 24 hours now and no feedback yet. Please SA i wish everybody can just see that this bank is just a money making business and that we all can move to a better more people friendly bank that care for there clients.
