800-236-3421

They called after 11pm.  I let it go to voicemail.  They did not leave a message.

This number attempted automated calling 5 times claiming to be an authentication service for Associated Bank in which I was instructed to press star. I do not bank with Associated Bank.

This number called me four times at my work phone, each one minute apart. The message left by them was an automated voice saying 'message deleted'.

Just for future reference, what happens is that an Associated Bank employee is trying to work from home.  The employee has to answer this phone call to do so.  And if they typoed their phone number and put in yours by accident, then you would see this automated call by mistake.  It's not a list or anything and you should just ignore the call.
