Sick and tired of pathetic service

<p>I have a business account with Fnb, for months now I have been having constant issues with them that they can never resolve when I complain. Monies come into my account and they take without reason, when I call, I'm told I have to log a dispute, as a business person I don't have time to be doing such as they supposed to realize that this is a business account and do the necessary. Hertz car rental went .into my account and took 7900 plus minus and then reimbursed me 4602 in which fnb took that whole amount, in the morning there was available 4602 which was a refund from Hertz, the bank took it and left my account in excess. In the afternoon there was a deposit of 4520 which yet again fnb took on top of the 4602, totalling to 9122, when i called them, they told me that they suspect that because the car rental took the money, i shoukd lodge a complain. My question is why should i lodge a complain? If they cannot explain to me why the bank has to take that money. I need this money within the next business day as I have a lot of debit orders coming in and accounts to pay, can someone look into this urgently, this is the last complaint I'm making or else I'm take my account elsewhere!!!</p>
