I went down there when I couldn't get through. They were not open on Monday. You shouldn't have any problems calling them now. I've recently called and I've been able to talk to them. They are making a lot of changes. I suggest if It's important and you can't get through then go over there. Hope that helps answer your question.
I had the same issue with them not answering EVER..SMH. you gotta go in person and be persistent
You may have to go to the Housing Authority they have open house on Thursday and be persistent don't give up
