Didn't answer because I had received a call from this number before as SPAM. I called it back and got a recording saying "the person at this number is unavailable." Did reverse search and got it is located in Arlington, Virginia and Its exchange 869 is managed by SPRINT SPECTRUM L.P..
The number is currently on switch number BTVLMDCKCM5 (switch is a technical specification for phone hobbyists) .
I won't answer if they don't answer! F . . . ing Spammers!!!
