SAR Passport Pick Up

Good morning,

I received a phone call in the last week of May 2015 from the DC Chisnese Embassy informing me to pick up my passport. I told the staff that I could not pick it up till the mid of June as my address is very far from the Embassy. I need to make arrangement in work. The staff told me she needed to ask her supervisor and called back. I have been waiting until today that she did not call back. And there is no phone that I can call to the Embassy.

My question is: how long will they hold my passport for me? Can I just go on 18 or 22 of June and they will have my passport for me?

Thank you for your attention.
