How much longer will she been in twin towers if she has been accepted for house arrest?

My sister turned herself in on June,22nd 2015 and is now booked in Twin Towers , Los Angeles CA. her release date is set for Oct 19, 2015. While in there she filled out the paper work to get on house arrest and she was qualified. Somebody has already called asking if she can stay with me while being placed in it and I told them "YES". He asked a few more questions and that was it. He also advised me it would take 4-5 business days for the paperwork to be processed. And so far its been 1 week. and she is still not out. What's taking so long? Should I be worried? Who can I contact? The operator # for Twin Towers they have no information to provide me but just the overall release date. They are no help!!!! Went in for 3rd DUI and added time for something else.
