Who called from 3475848466

Just received a call...didn't pick up as I didn't recognize the number.  I've had a ton of these calls today, each from a different number.  PITA!

Called twice, left no vm

Received a call. Did not answer. No message. Called back blocking my number.  Got a busy signal. Have blocked the number.

Called 2 times in less than 3 hours. I didn't answer  either time. I hate robocalls, scammers, telemarketing calls.

Same thing..call, no message.  Wife screwed up and called it back only to get a busy signal....scammer no doubt checking for active lines.  NC here by the way.
