They ask for my husband, I call back and it almost sounds like a cell phone answering machine, so I left them a really nice message, ha ha We'll see if they call back

they call and hung up.

They keep calling, but hanging up when I answer.  Aggravating!!!

Same # hit us twice today while at work...  no message either time, although there was a brief bit of silence before the hangup on the voicemail.

googled the # and this page was at the top of the list.   Bastages!

I only have a home phone for emergencies.  My cell phone is my primary number.  I see this number on my caller ID several times a day and I am on the do not call list.

I've done a bit of searching, and it turns out a number of people reporting this problem are Washington Mutual customers.  I called WaMu and requested that I be put on the no call list.  If they do not stop the attorney general is next.

It seems to go in cycles, some weeks they will call every day, up to 4 times a day, and as late as 9:30 PM!  Who does that?

They called my boyfriend today.  I asked who was calling (nicely) and they hung up on me.

I'd gather it's possibly a collection service, but no idea why they'd hang up on someone if they're after money.  Usually, collection services leave a message with just about anyone they can to get their money. ??

We're both WAMU clients, btw.

They called me three times today. The third time I picked it up and no one said anything.  I called the number back and I got a busy signal.  A few seconds after I hung up someone from that number called me back.

They have now called 15 times in the last 5 days.

I get those calls, they never leave me a message and am a WaMu customer also -- that's weird -- why would they do that?

I am also getting numerous calls as everyone has mentioned and yes I am a WaMu customer. They wake me up early in the morning and late at night. Sometimes up to 4 calls a day.  I went ahead and contacted them and requested the calls stop.  We will see....(they did not deny that it this # was theirs)

After blacklisting this number I receive the same calls from new numbers. It's time for group legal action. I have months worth of logs showing these fools calling multiple times a day.

Below is recent activity, leading up to the blacklisting of this number. Once this number called and was greeted with a recording of an official message stating "this number has been disconnected", a new number took over 8002075933. I have blacklisted that number now as well, and will see what new number they switch too:-/

I'm getting these calls, too! I have a Wamu credit card- but am not over balance or late...and when I answer I hear a couple seconds of shuffling papers or something and then they hang up. They always leave a 3 second voicemail of nothing but silence. Why on earth are they calling so often and not leaving a voicemail or talking when I answer the phone?! It's so annoying! Maybe they get paid by the call?

Did some more searching - found a global contact services website with this:
