Who called from 6237380965

Called and left a message...silent for a few moments until I hear "office?" in the distance.

Received 2 phone calls from phone number 623-738-0965 on my cell.  Not sure how they got my number, but asked for my son, and when I asked them how they got my number, they hung up.  I called back and they refused to take my call, but kept hanging up on me.

Called looking for my husband, advised I was his wife. Guy hung up. I called back and he asked for my husband again and then hung up....

Same thing here: Called (623-738-0965) looking for my husband, said I was his wife. He hung up. He called back and he asked for my husband again and then hung up again. WTF??
