WaMu Sucks!

We got a letter in the mail yesterday from WAMU that due to inactivity, they have cancelled our account. We are trying to be good consumers and not run up our credit cards and this is what we get. There reasoning was that we have too many mortgage accounts. Now, we have a first mortgage and a home equity line. Dont most people? How is that too many mortgages? I was livid when I saw this letter since my first thought was the credit score that is going to drop when there is $4500 limit missing. Has anyone had any luck with getting these cards back open?
