Fnb housing disappointed to refund me my available amount because im under debt review

I'm an Fnb client, I bank with Fnb and my bond is with Fnb too. I'm so disappointed with the way they treated me. I'm my bond account I have available amount that they can refund me. It's not a loan it's the extra amount of money that I paid into my bond account. I requested the housing department to refund me that available amount and they said they can't refund me that available money because im under debt review. I seriously don't understand that how is my debt review can affect my available amount of money that is paid upfront on my bond. I'm seriously disappointed because I'm doing a loan or anything I'm just requesting that funds that are available in my bond account for me. They told me they will only refund me after I finished with my debt review. Unbelievable and seriously need help on this matter. As far as I understand it's totally wrong because I'm not doing a loan. Extremely disappointed
