I sent a message to Brad, asking him to explain what has happened.
It may be he is ok, and it is in transit. The 20th of June until today is not a long time to not get your intake compared to some others.
Still not answering his phone is odd if he does indeed intend to honor your deal.
Since this was a postal MO if he is scamminh you, you have some good recourse, mail and internet fraud are severe crimes.
Let's see what Brad has to say though before you jump the gun.
