Who called from 8643741298

several calls, on several days. never a voice

Keep calling like every 20 to 30 minutes.. 6 calls since 2:00.  Anyone know who this is

I have received 6 calls since 2:00 this afternoon. Never leaves message. Just blocked the number

Got tired of answering calls every 30 calls so I blocked the number.

Just answered the phone after this number has appeared on my caller ID 6 times in the last hour!!!! Accented voice, male, possibly Indian. He had my first name. Said he was from US Auto Warranty Sales. I asked him to tell me why he's called 6 times in the last hour...... HE HUNG UP. Beware!
