Called this # back after they called me.   It rang about 3 times then it went silent.  I waited for 4-5 seconds then hung up.  It acted like it was some kind of ad.

Called, no message. Didn't answer.

called my number but didn't leave a message

They called and left a voicemail. The voicemail was 10 seconds long. The beginning was silence, then in the end it said:
"Hello? ... May I please speak with Akiko Auskitz?"

I will not be calling them back, probably a scam.

We received a call from this number today. She wanted to know if my husband could hear her. I immediately thought of the scam where they try to get you to say yes. Supposedly they are recording your yes, to use to buy things. My husband kept trying to get information. She said she was with habitat for humanity and was calling to say thank you for his donation. He made no donation. They called him by name and our phone number is unlisted. So, a questionable situation.
