Who called from 9133967458

I got a text from this number last night around 6:15 that said "Hello Kristy?"  I asked who's this and never got a response

Got a text and called the number back and it said that it was a text plus texting number... so it only does text messages... don't know who it is

I received a test from this number saying "hi Carol".  It reminds me of the spam I get sometimes saying "hi Carol" and no subject.  I never open them.

They text hi my name then asked if I had yahoo and to message them at txtflirty690 , I ask who never got a responce said their cell was dieing
