I'm a little skeptical of their doing this w/o notice. Probably, they mailed you something carefully designed to be ignored, and, it achieved its purpose.

Call and ask when the notice was given. If you are not satisfied with the response, send a polite letter to Wells Fargo President--see what they say.

If there really was no notice, immediately contact a class action lawyer. You may make money and so may your fellow victims. Unless the banks have to pay when they do bad things, they ain't gonna stop. @:-)
