They called. I didn't answer either.  They did NOT leave msg.

They just called me.  I used the option press 4 to see what would happen.  A guy came on and asked " are you deliwuant in your mortgage" I answer y asking him what company is this and he said it is "option one". I then asked where are you located and he hung up on me.  I believe they are scammers.  To fight back press 4 and ask them questions.  Keep posting what they are trying to do and maybe one day they will get caught or shut down., we need to fight back against these types of scammers once and for all.
