I've called numerous times at different times of the day. I've never spoken with a live person. 3 months ago I did have a man answer and he took all my information and said they won't call you back today and probably not tomorrow. I've yet to hear from them. The SSA.gov website can't tell you how much social security you will receive from an ex spouse. How does one decide when to file when you can't get answers?
