It's Possible he is ill or died like redrumloa said. I hope not, but it's definitely possible...........don't give him bad feedback or anything..........just wait and see................If I were you, I would mail a letter to his house, with his name on the envelope as well as Relatives: for example:
to:
John Doe or Relatives
86-23 blah blah Ave
Kentucky Fried Chicken, Alabama 11324
that way if he is sick or dea, this can call the attention of any relatives there, and they can contact you to explain.
