"I'm Su, thank you for your help yesterday, I'm near Irvine, can I invite you for a coffee this weekend if it is convenient?"
I texted asking who it was, that it was a wrong number.
They responded "After checking, I found out that I entered the wrong number, what should I call you"

I have had texts like this before, they try to act like it was an accidental text and then proceed to try to ask where you live, your name, etc. Do not answer them, it is a scam.
