the left hand doesn't know what the right hand's doing

the ˌleft hand doesn’t know what the ˌright hand’s ˈdoing

(saying, informal) one part of an organization, a group, etc. does not know what another part is doing: First I got a letter from them saying they couldn’t return my money, and then the next day they sent me a cheque. Obviously the left hand doesn’t know what the right hand’s doing.
