You should be able to the best time to reach them is early in the morning, before noon, and before 5. If you cannot reach the case worker go in and use the phones their by windows 9-13. The case worker will may come out. If that doesn't work ask the info desk or someone from windows 9-12 ususlly can help you out quicker. Just from what I see when I sit and wait there.
Go in and see them in person since you cant get in touch with them
