Exact same story here. Called twice tonight. I answered firdt call on third ring - they said nothing. I hung up, and left the house. Fifteen minutes later, call came in, went to voicemail, I just listened to msgs. Just a click where they hung up, no msg left. CALLER ID READS "ALERT"
The came in around 4:28pm. The caller id said "K2 Partnering S" . I didn't know the number, so I let it go the answering machine. No message left. Hung up before the answering recording ended. We never answer the phone for numbers we don't know.
