Who called from 2315974169

Received the following text message from this number:  "Verification Demanded for Validation Internet App".

I have no clue who this is and figure it can't be anything but bad.

they sent me a text with my name and address and a text saying helloz all good

I keep getting the SAME text but from a different number but the same weird spelling for Hello. It's creepy. There's no link so why are they sending these??
