Its Washington Mutual Card Services.

I have a WaMu credit card and received several automated calls from (281)504-0039. Finally decided to call WaMu at the number listed on my credit card (not the number they give in the call). They said they wanted to update my address and everything else is fine with my account.

wamu is calling me too because my mail got returned.  already don't them it was a mixup but guess that wasn't good enough.  my account is in good standing otherwise.

First time getting this number although, the other night I received a call from a 623 area code and The person on the line (in hindsight) seemed like he was trying to keep me on the line. Maybe like he was phishing for my number. I hung up.

Now I am getting calls from this 281 number in addition to 303 and 623 numbers.

Any idea on how to get it to stop without changing numbers?

The 281-504-0039 is WAMU Cards i got through on a call back to them and automated recording said contact them about the account.  so my guess is to call WAMU and tell them to stop calling you fro the 281 #
