You did not indicate what state where the Probate matter was handled. While it may be expensive, you may want to hire a probate attorney in that community in order to get your case handled in a responsible and timely manner. Good luck with this.
This is not a substitute for a consultation with an attorney with a background in probate law in the state where your Aunt was living.
I'm not sure from your statement whether the probate is being handled in San Francisco or if you live in San Francisco. You should be able to obtain a copy of the probate court's file on the matter (for a fee). Then, you should review the information in the file, and then consult with a probate attorney in the appropriate county where the probate petition was filed. The local attorney may have more luck getting a response from the public administrator.

I assume that you are a beneficiary. It should be part of the Court file if there was a Probate. You may want to consider getting the information directly from the Court. The bank records should have been lodged with the Court.
