Incorrectly deducting funds from clients account

A ********** cheque was deposited to my business account by a third party on Saturday 11 July 2015<br> The branch called to notify me of this on Monday 13 July 2015.<br> As explained to the consultant the funds were only reflected in the balance but not reflected in the available balance.<br> Received an sms last night stating R 25 000 was paid from my account from my available funds.<br> This was incorrectly done as the cheque had not been cleared and was therefore not refelected in available funds. <br> The consultant therefore made this in error but refuses to pay me back my money. saying that the cheque will clear in 7 days and only then will funds be available.<br> This is ridiculous as they have taken my own money. there should have been a zero impact in reversing the cheque.<br> No one seems to be able to help. and I need access to the funds today.<br> Absolutely disappointing, will close my business bank account due to this as it is ***** from the branch's side from removing funds from my account without my approval. Will definitely inform other business owners of this and the poor service from FNB in rectifying this.
