Who called from 6302191104

Got a few calls from this number over the past month or so , leaves a voicemail but it just beeps

Got a call this afternoon. I didn't answer. They left no message.

Calls every few days, leaves a voicemail that beeps about 4 seconds into message. Stop calling me.

I answered they said can you hear me.. I said yes they hung up. I remembered about the can you hear me scam and canceled my card on time :)

They called but when it went to voice mail, they didn't leave a message.
