Who called from 7178424988

got a txt message (called me by name) saying they hadn't heard from me in a while. I stupidly asked "who is this" and got the response If I want to know I gotta add txtieflirter39 on yahoo messenger.  I'd like to block the sender but my phone provider doesn't do that easily....hope they aren't snooping on my texts...how did they get my name?

I got the same message. I bluntly told them that i wanted to know who it was. i went onto my yahoo account and blocked this person. Do you have any leads to it?

I got the same txt i asked who it was but no responcejust the same mesaage like ten times.

I got the same thing. Really irritating because I don't have a Yahoo account so I'm unsure of where they got my name AND phone number.
