Just got a phone call from them. I am not a customer of theirs, nor have I ever been. But they called and said I missed a bill payment when I don't even go with them.

I got a call from this number and they left a message on my voice mail..it sounded like a helicopter and heavy breathing. this has happened twice. if this is wamu's way of getting a hold of you about checking account options and etc. I think they should try another way. a message with loud roaring noises and sounds that sound like heavy breathing does't tell you anything. it just annoys you and you'd never want to call it back.

Received a call today from WAMU and they left a message to call them at 866-397-4904 or go to the web at www.MAUMcanhelp.com.

I get calls from this number ALL the time, and don't leave any kind of message. I don't have overdue bills, so there's NO reason for phone calls. I don't pick up these phone calls.

Washington Mutual or IC Systems also the following numbers:
1-800-561-5695, 1-972-244-6538, 1-347-584-2059, 1-404-267-0006, 1-951-892-7400, 1-412-595-9025, 1-214-233-7251, 1-770-240-0000,1-954-377-0257 and 1-858-384-1164.  I know there are more.

This is completely ridiculous!!!!!!!!!!

This is a scam number. When you call this number a recording voice will ask for your account number and password. And then hangs up.

I'm not a WaMu customer and got a automated telemarketing call, probably random digit dial. I'm on the DoNotCall list. They must really be desparate with the hit they've taken on subprime. I'll never sign up for them now.

me too they just called me but i was thinking it was a scam

425-507-0644 keeps calling day after day. There is never anyone on the other end. From the other posts, I do not have an account with these people nor am I past due on anything.

It is Washington Mutual trying to sell you more services.  Some other numbers you may see are:
775-332-0228
480-296-0235
I just told them to remove me from their lists.  If you call back and keep hitting "0" you will eventually reach a real person.  I am a new checking account holder and they are using my contract info to sell me other services.  
I have received almost 20 calls since Saturday.  Good luck!

I have a wamu account, but my account isn't past due, but went over the limit this month by just a few dollars, so they started calling.  they continue to call me--sometimes they leave messages and sometimes they don't.

this is washignton mutual, wich is a credit card company and you have a past due bill

Got a call from this number also.  I have no idea who it is.

caller i d said washington.
