"OBee CU Alert:  Your CARD has been DEACTIVATED.  Please contact us at 360-539-5306 to REACTIVATE your CARD."

Who the heck is OBee CU and how did they get my phone number?  Googled their phone number, it seems to belong to aurigma.com, although it is not the company's main number.

Conclusion:  this is a SCAM.  I am ANNOYED.  I am NOT going to CALL them.

Correction:  further Google search indicates OBee CU is an Olympia, WA area credit union.  The phone number probably used to belong to an aurigma.com branch office, was disconnected, and was then reconnected to the bank.  Possibly.  I'm speculating.

The fact remains, I've never heard of this institution before, don't have an account with them, don't intend to call them.  However, it's POSSIBLE this was  a simple WRONG NUMBER and not an outright scam.  Maybe.  Regardless, it's still annoying to get quasi-threatening text messages from unknown entities.

Final correction:

I called the bank named in the text message and they confirmed:

THIS IS A PHISHING SCAM.

The phone number in question does not belong to the credit union.  If you get this message, do not call the number.

I just got this text right now as well.  I don't plan on calling

Yep, I just got a text and have never heard of OBU CU.  When you call the number it says select option 1 to reactivate your card and it asks you to enter your card number.  I am sure this is a scam to get your card number!
Makes me mad!
