Who called from 7023580397

Calls on my land line and also my cell .where do they get both numbers

Got a call from 702-358-0019. Said they wanted to invite me to Las Vegas. Told him I was on the do not call list. When calling the number back, I got a message saying the number was not in service. Reported number to the FTC but won't do much good when all these numbers can be spoofed these days.
