Who called from 7182857489

I received a text message from this number as well..and the address me by my first name.. I don't know whom it is .. I checked around a bit and came to the conclusion that it some kind of scam related arrangement.. they wanted me to add them to Yahoo instant messenger as well..

I also got a text from them saying Heyyy "first name". Based on the above, I am not replying.

This exact thing happened to me as well on the same day...:(

Same thing here, they said" hey the chase"but no response back when i asked who is this?
