Caller stated he was from opportunity financial loan company, never heard of them before

I keep getting calls and messages . I have not applied for anything.  Some loan company calling me to finalize the details. What details?!  Now I am scared someone is trying to get  a loan in my name.  Geez--does it ever stop. I am so sick of all this crap.  I guess keep posting on these websites and maybe join together later for a class action lawsuit.  I hate doing that but we need to send a strong message.
