Got a double text saying "heyyyy and my name"

Received a text from this number...and I repeatedly asked who is was because I did not recognize the number...I never got a name or anything....

Got a text saying 'hiiii and my name'. I asked who it was and they told me to add them on yahoo messenger and their name on there is miawoman45. I asked who it was again and they said 'sorry i have no battery life', i then asked again who it was and recieve no response.

I got that same response but different number!!
I find weird how different numbers say the same answer when you ask who it is
