I don't have experience as far as mental health, but I do with "regular" health issues (severe enough my DS was hospitalized, had surgical intervention, etc..). RELAY CONVERSATIONS seem to be the norm in the american health system. To me, it is EXTREMELY UNEFFICIENT and FRUSTTRATING.
Like you said: don't this people talk to each other???
Try to stay very calm and try to document your conversations (day, time, who and topic). If you feel you are not going anywhere, pick the person that is "most" incharge and relay all of the conversations and information through a letter or an e-mail . If it is in writing, it just has more power.
I don't believe you can fight the system (or should waste your energy on it right now), but you can make sure it runs a little bit more efficiently and make people accountable. Try also to stay very formal.
