As most things these days, the do-not-call list has been totally compromised for these GARBAGE calls that want to verify your phone number as an active line for some reason--haven't yet determined. My new phone has a number blocker but they(the computer making the calls) just morphs into a new number and fills up the blocker. The war goes on. Please keep posting experiences so we can get an idea of who or what is going on with these numbers.
I have received two calls from this number in the last two days. One voicemail and one answered both times it just said "This is a service verification we will call you back later"
Same as Brent. Service verification. Last evening and just now. I used to get these regularly but must have been a different number or I reckon there'd be entries here.
