Home Loan Interest Penalty

I app**** for a bigger bond on my home loan and a transfer of my fathers 50% in the property to my wife. I wanted to use this money for home renovations. Standard Bank advised that it is better to apply for a new bond. I knew that it had cost implications but did not keep in mind that Standard Bank has penalized me with R30,000 interest as I have not let them know that I want to settle the bond 3 months prior. As this is in their rights to do I do not have any recourse, however I would have thought that the bank may write off this amount as I am in effect just transferring 50% of my property with together with a bigger same loan amount at the same bank. I am very dissapointed in Standard Bank.
