Who called from 3478942639

Called me at work.

Yes. I've gotten this call repeatedly. Scam I'm sure but I either don't answer or pickup and hangup.

Call back gets 30 seconds of silence, followed by busy tone then disconnect.  Clearly not a "legitimate" company.  As gatorjl said, a SCAM of some sort.  Block it.

Has called landline repeatedly. Have kept checking to see if it was listed anywhere...glad to confirm this is a fraudulent caller.

Thanks for posting this - I have now blocked the number.
