Solvable Adoption-related Problems

Here at the Center we've heard reports of, and assisted many families with varied adoption-process-related problems. Issues we've heard about are calls that never get returned, being passed over in consideration for a child for no stated reason(s), or other communication-related problems. I'm sure that there are other issues, but for now let's focus on communication. 

What problems have you faced in this area? I would welcome answers from both sides, the professional and the potential family. Do you have any concrete solutions to resolve these type of issues? How could the Center help you (again this is for people on either side of the equation)? How can we work together to solve these issues?
