Got a text message from this number.  No idea who it is and did not respond.  The message said "heyyyy" followed by my first name.

Same thing. Don't know how they got my name. Likely a scam.

Same here. Won't text back.

I got the same text message it said heyyy then a name which isn't mine. Then i texted back saying that they must have the wrong number, they texted me back and said " :) a.dd me on y.a.h.O.O IM id is brookewoman35" they won't stop texting me and im getting very irritated! They keep saying the same thing but giving off different IM id's. I said stop texting me they replied with sorry im out of service :(
Anyone find out how to block this number let me know!

I am having the same issue! Just got another one today. Anyone know who is doing this? Have you tried to call? Not sure if I should or not.
