Not a call but an initial random text, received on a Sunday afternoon, in Spanish, asking for me by name and if I could come in on Monday? I texted back, in English, asking who this was and received the reply "Ricardo." I don't know anyone by that name. I texted again asking who this was and what it was in reference to and received the reply "sorry." I did not text further. Unsure if this is a scam or not.
