Who called from 6613760474

doesn't leave a message

Call from this number, doesn't leave a message.  3-5 times per day, blocked it.

This number shows as Out of Area and calls every 15 to 30 mins started last night 4/26 and again tonight. They don't leave a message. they are relentless!!  They have now been blocked!!

They have a strange pattern: two calls placed one minute apart, and then a third 5-8 minutes later. They've called 12 times in the last two days. No message. Now blocked.

Same thing for me. calls constantly, very closely together. Very disruptive of our evenings. We never answer unknown numbers.
