Unreasonable Amount for a mistake!

I have a Savings Account and a Fixed Account with Capitec Bank. My maintenance money gets paid into a different bank with whom I also have an account. By mistake, I transferred the maintenance money from the other bank into my Capitec Fixed account instead of my Savings account.<br> <br> For the amount of R 1650.00, which I paid over into the wrong account (Fixed), they charge an unlocking fee of R173.92 in order to transfer the R 1 650.00 into my savings account. This is more than 10% of the amount I wrongly transferred and probably more than all the interest I have accumulated since I opened the Fixed account last year.<br> <br> I am very upset about this, because it is not as though I wanted to take from the money already in the Fixed account (which is on the fixed term until November), I only wanted the one transaction corrected and put into my savings account.<br>
