To everyone who is having problems with WAMU:
I have also had some problems and did some research. You can actually report them to the feds and they will investigate. Though it takes a little while - it WILL be helpful if everyone who has a complaint contacts them.
You should contact:
San Francisco Regional Office
2001 Junipero Serra Boulevard, Suite 650
Daly City, California 94014-1976
Telephone: (650) 746-7000
Fax: (650) 746-7001
Mail: P.O. Box 7165
San Francisco, California 94120-7165
Good luck with your problems in getting them resolved!
