2 calls in quick succession from 1-408 6489372 8. They think they are bypassing the identifying phone number by adding the 1 in the front and an extra digit at the end.  They asked for me by last name.  I answered in Spanish so they hung up.

I got a call from +40-864893728 which I did not answer.

Strange looking number blocked immediately.

Called with the extra digit showing on caller id - blocked them. Surely a telemarketer.

Received 7 calls from this number, 14 086 489 3728 one identified as Luna Marisol in the past 4 days.  The caller's number is identified differently on my caller ID -- sometimes with spaces, others without, most with the number 1 in front of what looks like a 408 area code -- but I think it's an international call.
