Complaint Review: Washington Mutual Credit Card

I have had my WaMu credit card for just under a year. My account is and has always been up to date and current.

Since I have a small limit I recently called and requested a credit increase. I was told WaMu periodically raises or lowers limits based also on the amount of time you have had the account and not upon customer request.

Less then two weeks after I made the request I recieve a letter from WaMu saying my account had been transfered to Columbus Bank and Trust Company. I am filling this report to ask am I the only one this has happened to? Also, is this legal?
