Who called from 4174474530

Hang up upon answering.

Same thing,  but called 3 times in 8 hours.

This number called my Cell Phone.  Is there a way to block this number on a mobile?

They are actually this company.

One can only assume they are a scam company since apparently their idea of a lead is that it is an active phone number they have called.

I keep getting the call and then a disconnect.  It calls my cell phone every 30 minutes
