. . . or it's a 3rd world criminal faking their caller ID to extort personal information, or money out of you. Right? Never give out any information on a call you did not make, or to a number you did not verify as real. Never return calls to numbers given to you in a text, fax, email, or phone message until you check them out.
Sprint does not call you especially from a local number I called sprint to ask about this because I didn't trust it sprint said they send texts only and you have to call them so this is some kind of scam! Who knows who's doing it !!!
