Who called from 2678288051

[***] keep calling and leaving no message. I never answer ,just let it go tovoice mail.

Caller ID says: "Unassigned"

Called my landline once (this afternoon).  They did not leave a msg.  When I called back, I was immediately put on hold - wasn't worth my time to try and get off their 'list', so I hung up.

They keep calling me every day.  There is no reply frim them.  No answer when I try to call them back.

Yes, this is a phone number for Frontier Energy.  They are stalkers.  I just blocked them on my phone!   Annoying!
