According to this report the ZC did not entertain the request from the BCB, which is well within their right I suppose. But apparently the ZC are further cementing "home field advantage" by not providing a tour match. Didn't they also pull some poor hosting with the hotel or travel arrangements during our last tour?
I think the only proper response to such poor treatment of guests will be to humiliate them on the field of play in their own backyard.
