what is wrong my AP application?! help

The receipt date of my AP application is April 18. CIS is working on the case after April 17. From CIS public website search, my case is under pending. For a family emergency need, I need to get my AP ASAP, so I went to local immigration office, the offiicer told me that my AP "was approved at some level on May 5, the final notice was not sent out yet"; at the same time, I also called the immigration 1800 number, I was told that my case was approaved on May 5,and was sent out on May 7. So confusion. The local office could not do anything since it was approved.... I sent out fax and calling... nothing happened so far. Note, May 7 was a Sunday, how come the approval notice was sent out atthat day, I do not know how to handle it........, my father is in hospital, I need to see him ASAP....

Any suggestion? similar experience?
