Who called from 4012845683

Got a text saying, "hi Kate" and I replied, "Sorry, who is this?" and they replied, "do you use Y .ahoo messenger?? cause im me my id is txtchick7"

...so yeah I have no idea who this person is and they didn't respond to inquiry.
I don't use YM, so ...? Spam bot I suspect.
