What should I do? AP and EAD more than 6 month

I applied AP and EAD based on 485 September 2008, but till now haven't been approved.
I went to infopass three weeks ago. The local officer e-mailed the processing center and said should be approved within 2 weeks.
I went to the local office again this morning. What they did was e-amil processing center again.They asked me to wait another 10 days to see what happen.

What should I do next?

Thanks!!!
