Realtors in Orlando, fl: is it legal for a realtor here to remove a forclosure home from the mls before sold?

My family went to look at a home that was gorgeous, perfect price, and forclosured. It was being sold as is and by REMAX. So someone from REMAX showed us the home, but it wasn't the selling agent. My family put in an offer a day or two after looking at the house. While waiting for the bank to get back to our realtor on whether they accepted our offer or not, we noticed it was taken off all the listing sites it was on except one. The sign was/is still in the front yard but what us and our realtor think happened was the selling agent found someone to put in an offer, took it off the mls, and then delayed in turning in our offer therefore the bank accepted the other peoples offer instead since ours wasn't turned in on time because of this realtor doing something unethical. Is there anything we can do about this? And is she allowed to do that? Thanks so much.
